Good afternoon, ladies and gentlemen, welcome to our Interface Talk. My name is Klaus Böhmer and I am responsible for the Business Unit Interface Electronics. And I am pleased to introduce my colleague Uli Hempen. Thank you very much, Klaus, for having me here as well. At WAGO, I am responsible for international Market Management, for the growth of our products in the industries in which we operate. Today we would like to talk about power supplies, energy meters, so products that are basically used in all industries where a control cabinet is necessary. Absolutely, no automation solution without an power supply. We have different performance classes: Eco 2 for basic and standard applications. And on the other side Pro 2 our high sophisticated power supplies. These are devices that offer high efficiency in a small assembly space and also enable communication to the PLC. I believe that communication is an important feature in the area of digitalization, in the smart factory. Components are increasingly networked, not only to control the system, but also to observe and monitor systems. And that goes all the way into the control cabinet. Now we have developed power supplies which provide the internal measured values via communication interface, you can monitor almost every parameter that is located in the power supply. Absolutely. Exactly. But I would say we let our experts speak. We would like to hand over to Stefan Wagner and Frank Sellke. Hello, my name is Stefan Wagner and I am Product Manager for power supplies at WAGO Kontakttechnik in Minden. Today I would like to introduce you to a whole range of new products, first and foremost our power supply Pro 2. Which are powerful, compact, efficient, reliable and also communicative. Next the Ground Resistance Signaling Module. A unique module that can detect dangerous earth faults in advance in control circuits and thus significantly increase the reliability of the power supply. In addition, the power supply Eco 2, which is intended for standard applications where only 24 volts are needed and yet reliable, efficient and compact as well as cost-effective power supplies units are required. Last but not least, the electronic circuit breakers in single-channel design, which offer a whole range of features in a width of just 6 millimeters that provide our customers a real added value. The Pro 2 power supply family is growing. Thanks to their modern circuit design, the devices have a high efficiency and thus lower energy consumption, and the carbon footprint is also reduced. Thanks to the high efficiency, the devices also have a lower heating and can thus be built in a more space-saving way. The components in the device are also subjected to less thermal stress, so that the devices are robust and durable and also can withstand shock and vibration much better thanks to the compact design. A temperature range of minus 40 degrees to plus 70 degrees Celsius is thus possible. And derating only starts at plus 60 degrees Celsius. What makes these devices special is their communication interface, which can be found on the front. On this device here, the communication interface is clearly visible, via which, for example, a PC or laptop can be connected with a USB communication cable for direct configuration or for monitoring on site. But it is also possible to snap on so-called communication modules on the interface and thus connect to the device via different protocols. This makes monitoring possible, i.e. to diagnosing errors, states or warnings at any time, detecting anomalies and thus performing predictive maintenance. On the other hand, it is also possible to parameterize and make setting in the device such as the overload behavior, the output voltage, the signaling. We can see how this looks in detail in the device's software. With the WAGO Interface Configuration Software G2, WAGO offers a tool for configuration as well as monitoring of the WAGO Signal Conditioners and the WAGO Power Supply Pro 2, which also comes with a simulation in the current version, so that you can get an impression of the performance of the WAGO Power Supply Pro 2 without owning a Power Supply Pro 2. We select a WAGO Power Supply, e.g. the 10 Ampere device with a current firmware and connect to the device. After connection, we have the possibility to read out measured values from the device. Here is no load connceted to the device, therefore we see the voltage and just no current. Within the settings we can set an output voltage, but also configure the overload behaviour. However, this is also possible offline. To do this, I simply select another device with current firmware and then go directly to the settings. Adjust the output voltage here and now go into detail about the overload behavior. With the overload behavior it is so that we can select just certain characteristics at the same time, e.g. we can choose a constant current, which is very useful if you want to charge a capacitive load, a Hiccup mode or also the behavior of the electronic circuit breaker, which I will discuss in more detail later. And additionally PowerBoost and TopBoost can be selected. Now you may ask: What is this good for? This helps you to adapt the overload behaviour to your load and your conditions on site. The TopBoost is used when you are using miniature circuit breaker on the secondary side and want a faster trip in the event of an overload or short circuit. Then the TopBoost provides up to 600 % output current for 15 milliseconds. The PowerBoost is good to cover starting currents or to provide more power in case of rapid load changes, which is here 150 % current provided for 5 seconds, beyond the nominal current. The electronic circuit breaker, in turn, is a feature that helps meet the requirements of the Machinery Directive. This means that EN 60204 requires that dangerous earth faults are switched off within five seconds. If, despite TopBoost, the circuit breaker cannot be tripped within 5 seconds, the electronic circuit breaker helps to meet this requirement and to disconnect the dangerous earth fault by switching off the output of the power supply. For this purpose we have the possibility to configure the tripping current and also to set the tripping time. If I set this to 5,000 milliseconds (5 seconds), I have definitely fulfilled the requirement. I close this setting and switch to the simulation mode. In the simulation I can now start the power supply and immediately a graph of output current and output voltage runs here. Here in this area I can simulate the connected load and if I now have a load of e.g. 40 percent or 50 percent, with a 40 ampere power supply this corresponds to an output current of about 20 amps. You can see here that the output voltage drops slightly. This is due to the configured behavior "Active Droop". This means that as the load increases, the output voltage will drop slightly to allow the power supply to be connected in parallel. If I want to have a constant output voltage with changing currents, I just have to deselect this behavior. Now let's simulate the effect a short circuit has. We now see an overcurrent. Here we see a short peak, this is the TopBoost, which was "fired" so to speak, and after that we have an overload, which is then completely switched off after a short time, within five seconds. In this way, we have easily fulfilled the requirement of EN 60204 to switch off dangerous ground faults within five seconds, even if the circuit breaker has not triggered yet. One more interesting thing is indicated here below, that is the possibility of taking a closer look at the communication that runs via the fieldbus. To do this you can select e.g. the Modbus RTU and then you see what is shown here in the simulation window with the values, the measured values, but also with the operating states, warnings, errors and so on in table form and so see the registers assigned to the corresponding values. We think a very good help for the programmer or the PLC programmer, who can easily retrieve or write down the data from the power supply via the corresponding fieldbus or protocol. In 2021, the portfolio of WAGO Power Supply Pro 2 grows continually. In addition to the single-phase devices with output voltage of 24 volts and currents from 5 to 40 amps, there are also three-phase devices with output voltage of 24 volts and output currents 5 to 40 amps. In addition, voltage variants are now offered with 12 volt output voltage and 48 volt output voltage. The 48 volt devices are available in both single-phase and in three-phase versions, and a three-phase device with 960 watt of output power is also included. In terms of the approvals, there is now UL HazLoc approval available, which is hazardous locations, that means in the American area the units can now be used in explosive environments. And another approval is for the maritime sector, the DNVGL approval, which allows the devices to be used on ships or onshore/offshore. A good combination with these approvals is the so-called coating, i.g. the protective coating, which reduces the oxidation of the devices and thus makes them resistant to harmful gases or e.g. salt spray. Among the communication modules, there is a new module with Modbus TCP, which also speaks Modbus UDP and has a web server with http and https on board. Of course, this module also has security mechanisms on board, so that the user can be sure that his data will not fall into the wrong hands. Hello, I'm Frank Sellke and I've been working in global sales for WAGO since 1994. Today I'd like to talk about a new product that takes away the horror of ground faults in your machines and systems. The Ground Resistance. Signaling Module 789-665. Every machine builder knows the standard IEC 60204-1, machine safety, electrical equipment of machines. Chapter 9 says about insulations faults: Measures must be taken to minimise the consequences of ground faults. Method A describes the grounding of the control circuits on the 0-volt side in conjunction with a fuse on the 24-volt side. This is a widely used approach: A simple wire from the power supply 0-volt connection to PE. Ground faults to the 0-volt side are parallel to the wire and are aggravation. Ground faults to the 24-volt side create a short circuit on the detour via ground, which triggers the fuse and the machine then stops. The advantage of the wire: It is the most cost-effective fulfillment of the standard according to method A. Big disadvantage, however, the ground fault leads to sudden failure of the machine without any warning. High consequential costs due to loss of production can occur. And this is exactly where we come in with our new product. With a small investment in a Ground Resistance Signalling Module, in addition to compliance with the standard, you now have the chance to detect imminent ground faults at an early stage and thus gain a time window for preventive maintenance measures. We see here the course of the insulation resistance over time. Ideally high at the beginning, it drops over time due to aging and damage to the insulation, until at some point down here the fuse trips and the machine is shut down. If you detect poor insulation resistance before then, you gain that window of opportunity for preventive maintenance that can prevent loss of production. Then I would like to briefly explain the features and advantages of the module. We make an automatic measurement in grounded mode in 10-seconds interval. In this case, 0-volt and PE are connected for 9.5 seconds, as in case of the wire, and for just under 0.5 seconds the connection is disconnected for measurement. There is a clear LED signaling of the ground fault with red and green LED and with two yellow LEDs whether the ground fault has occurred on the 0-volt or on the 24-volt side. Additionally we have a potential-free contact for signaling the ground fault to the PLC. Here the operating mode can be switched to ungrounded circuits. This shortens the measuring interval to 1 second. However, this module is not an insulation monitor according to IEC 61557-8. The measuring interval of one second in this ungrounded operating mode speeds up troubleshooting and the circuit affected by the ground fault can be found ten times faster. At all connection points we have fast Push-in technology suitable for all types of conductors and an individual labeling can be done via adapters in two places. Give yourself and your customers the opportunity to detect incipient ground faults with the Ground Resistance Signaling Module 789-665 and thus avoid high production downtime costs. Thank you and goodbye. Many applications are standard applications where only 24 volts are needed. This is a good use case for the WAGO Power Supply Eco and our extension of the Eco family: the new Power Supply Eco 2. They are compact, durable and also cost-effective. Cost-effective in three respects: firstly in the purchase, then in operation through reasonable efficiency and in commissioning thanks to good connection technology. For the connection technology, we have been inspired by the 221 connection terminal, which ensures an intuitive, quick but also reliable connection. We have transferred this to the WAGO Power Supply Eco 2, which, as you can see here, is equiped with levers and also with a Push-in connection technology, so that rigid conductors, conductors with ferrules or ultrasonic compacted conductor can be plugged in directly. The Power Supply Eco 2 initially comes in two power classes in 30 watts, 24 volts and 120 watts, 24 volts and in single-phase. They have efficiencies of about 88 percent and 90 percent. And they are energy efficient thanks to the good efficiency, have lower power dissipation and therefore longer life. On the other hand, the lower power loss means you can build more compactly. That means you save even more space in the control cabinet. The devices have a DC OK LED and the 120 watts device also comes with an overload LED and a DC OK contact. A nice thing for labeling are these labeling adapters that come with each device and allow you to lable with a TOPJOB S labeling strip, which you also know from the terminal blocks, the device quickly with a printer and thus clearly identify the place of use. The devices also have all the necessary approvals for the world market, such as the current UL 61010 or the EMC standard 61204-3 in the latest 2018 edition, so that they are also future-proofed with the Eco 2 Power Supply. In today's machine and plant engineering applications, fine-granular protection in control circuits is becoming more and more common. The requirements are clear: You want to have a reliable protection of the circuits, with diagnostics and save space at the same time. This is where the Electronic Circuit Breakers from WAGO come into play. In particular, the single-channel electronic circuit breakers, which combine a whole range of features in a six millimeter housing. There is, for example, protection against short-circuits and overloads, but also protection against dangerous ground faults according to EN 60204, which every machine and plant builder knows. We offer these to single-channel Electronic Circuit Breakers with currents of 0.5 amps to 8 amps and have the once in fixed setting, that is, 0.5 amps, 1 amp, 2 amps, 4 amps, 6 amps, 8 amps fixed or with a variable setting means from 1 to 8 amps in one amp steps. In this was the circuit breaker can be adapted to the specific application. The circuit breakers can also be operated series. For this purpose, jumpers are used which can be pushed into the jumper shafts. Up to 10 circuit breakers can be interconnected in this way. Thanks to the digital output that they have, the devices offer the possibility of running a diagnosis, e.g. whether a channel has tripped. You can also connect this together and then query it as a collective message. On the other hand, there is a digital input that allows a reset remotely or a channel to be specifically switched on or off in order to use the circuit breaker as an electronic relay. Last but not least, the adjustable circuit breaker can be configured to also have a current flow monitoring function. All these are, we think, added values for you in your machine or plant. Thank you, Stefan! Thank you, Frank! That was very impressive to hear again what kind of performance our Power Supplies are capable of. We have brought along a second topic, which is now about energy metering. A huge topic: energy metering. Energies are rising, so power generation, electricity, distribution are becoming more expensive. In this respect, energy measurement or any energy conservation at all is a big issue in industrial production facilities. And what I don't measure, I can't control. In this respect, Energy Meters are needed. And no longer the big ones, but the small, smart ones. And that's where we've come up with some new ideas. Absolutely. Well, there's one point you haven't mentioned yet. It is about the carbon footprint. All companies are required to find out where energy is actually consumed and where CO2 is ultimately produced. And our Energy Meters are absolutely suitable for this, they are calibrated, are capable of billing and are therefore ideal for applications in industry or in buildings. Yes, they also have other features in addition to being calibratable, such as the operation. I can operate the meters with the display very, very easily. But I can also configure them quite easily with the smartphone. That makes the whole thing smart to handle, right down to the simple connection technology. And here I would say we hand over to our expert Michael Meyer. Hello and welcome to WAGO. My name is Michael Meyer and I am Product Manager in the Business Unit Interface Electronics. Today I would like to introduce a new product highlight. The WAGO Energy Meter with MID certification. Today I would like to talk about the following points: What makes these Energy Meters so special? The key features. How is the Energy Meter configured? The smartphone app. And where is the Energy Meter used? The applications. What actually makes the WAGO Energy Meter so special? It is the first DIN rail-mounted Energy Meter for billing with a spring connection technology. And here it is not an ordinary connection technology, it is Push-in technology with lever. The advantage: with a fine-stranded conductor with a ferrule I have the ability to simply insert the conductor into the terminal point and the meter is wired. I also have the option to protect the meter against manipulation. Here I have the cover cap that I can put on the meter and can seal it. The 4PU and 4 PS Energy Meters, as we we call them, differ in the connection. 4PU for universal and 4 PS for straight. The universal meter is wired from below and the straight version is wired through the meter. Both meters are direct meters up to a maximum of 65 amps and they can be used in 2, 3 and also 4 wire networks and are suitable for 230/400 volts. In mid 2021, the product portfolio will be extended with the WAGO Energy Meter for current transformers. Compared to the direct meter, the transformer meter comes in two division units, 36 millimeters. And that is called real space saving. The suitable current transformers are already available from stock. With this new generation of meters, we are talking about real communication professionals. And why is that? We have integrated a Mbus interface, a Modbus interface and two S0 interfaces for supply and purchase in one meter. We call it the 3 in 1 solution, three interfaces, combined in one meter and this offers maximum flexibility and also a reduction in storage space at the end. There is an extensive tariff selection for the relialbe recording of working values and also of individual consumers. This can be easily switched by an external 230 volt tariff input or a switchover is possible by the Modbus interface. This allows you to switch between high and low tariffs, for example. Full transparency at a glance. The illuminated display, required by the MID directive, offers the user on site all quality characteristics for all three phases at a glance. To give an example: Current, voltage, mains frequency, power factor and power for all three phases. Configuring becomes intuitive. The configuration and operation of the new WAGO Energy Meters is done through sensitive controls, which are marked here below, through three green dashes and on the other hand, the user has the possibility to configure the new Energy Meters via a smartphone app based on Android and also IOS. This is done via Bluetooth communication. Furthermore, the user also has the option and can save all the measured values that the meter provides as a CSV report. Now I would like to introduce the WAGO Configuration App for the new Energy Meters. Before I start the app, I have to put the meter into Bluetooth mode. This is done via the sensitive controls on the meter. To do this I have to press and hold the sensitive controls for 5 seconds. After 5 seconds, the Bluetooth sympol appears. I confirm this again. You see a QR code here, which I can scan with my smartphone or tablet. A connection to the meter is then established. Now I am connected to the WAGO Energy Meter and you can see the connected Energy Meter in the overview at the top left, underneath three tabs, the energy values, standard measured values and the option to configure or set the Energy Meter. Let's take a look at the energy values. The energy values are listed here neatly below each other. Then we look in the menu, where we can see the standard measured values, e.g. the voltage per phase L1, L2, L3 or also the current for the phase 1, 2, 3 and I have also the possibility to save these values as a report. You can see the small floppy disk up here. I go on it once and at this moment I can save all the measured values, a so-called snapshot, as a CSV report. The advantage: I can provide this snapshot my operator for billing. Another menu are the settings, Here I can configure the Modbus parameters, such as the Modbus addresses, the baud rate, the S0 pulse rate and many many other things more. An example I would like to show now: I have the possibility to rotate the display by 180 degrees. I will do that once now. The advantage is: If the meter is used in another mounting position you can still read the values. You see the display is rotated 180 degrees. Where are WAGO's new Energy Meter used? The new Energy Meters are used wherever energy consumption needs to be recorded and billed. The keyword here is submeetering. The Energy Meters comply with accuracy class B according to the MID directive and are suitable for use in industry and building. The following three main applications are intended to give you a brief overview how versatile WAGO's new Energy Meters can be used. The first application: charging infrastructure. The goal is to ensure transparency at wallboxes and charging stations. Here, the keyword is the determination of the carbon footprint. To underline this with a small example: e.g hybrid company car, which is charged at home and the employer reimburses the costs. Here you have the option to simply provide this determined data via a CSV report via the app. Another example is the charging station on the company site. Here, the consumption can be easily read out via the app, too. And made available as a CSV report. Another application is the order-related production. This is a measurement of the energy consumption of producing machines, manufacturing cells, etc. For the calculation of products or for the delimitation of energy consumption, the energy consumption of external companies can be determined to reduce the EEG apportionment. Another application is the distributed properties. Here it is about the individual billing of the energy consumption per tenant. Here as an example the operator of a shopping center must bill the integrated bakery. Here you have the advantage to bill the energy consumption precisely via the meter. Thank you very much, Michael, that was also very impressive, what we have learned now about the MID Energy Meters, really a great family. Together with the Power Supplies, I think we have developed two product areas and brought them to the market that are really fun. May I thank you for your attention, Also again from my side, thank you very much for your attention to these exciting topics. I think Power Supplies and Energy Meters have such a wide range of applications. It is fun to see and use such a wide range of products. From small to large, everything is there. So come to WAGO, because we will help you. Yes, thank you again. Stay healthy and all the best until next time.
