Beckhoff’s EtherCAT terminals offer process control, power monitoring

Beckhoff Automation has introduced the new EL34x3 series EtherCAT terminals for power measurement and mains monitoring. The new I/O terminals offer basic monitoring of the energy supply network and process control to high-end power monitoring.

The EL3443 three-phase standard power measurement terminal is suitable for all process control tasks. It offers mains monitoring functionality, precise determination of zero voltage crossing, and harmonics analysis. It also is suitable for DC systems.

The EL3453 three-phase terminal for measuring voltages up to 690 VAC handlesmore demanding process control tasks. The terminal updates its process values with every half-wave, which corresponds to an interval of 10 ms at 50 Hz.
