EL3783 Beckhoff EtherCATBeckhoff releases EL3783 oversampling EtherCAT Terminal for power monitoring for standard control systems. Conventional automation and power measurement technology are increasingly converging, and with the integration of the EL3783 I/O terminal, high-precision grid analysis becomes available for a range of power-generating systems. Most importantly, three-phase AC voltage systems up to 690 V can be analyzed simultaneously on six channels and with 20 ksamples/s directly in the PLC. For each of the three phases, the EL3783 samples voltages up to 400/690 Vrms and currents up to one or five Arms as instantaneous values with 16-bit resolution. The six terminal channels are evaluated simultaneously based on the EtherCAT oversampling principle, with a temporal resolution of 50 µs, which is significantly faster than the cycle time of the controller. Using the EtherCAT distributed clocks functionality, it is also possible to measure synchronously (<< 1 µs) with other EtherCAT devices in systems of virtually any size and precisely detect propagating grid faults.
