EL3783 | Power monitoring oversampling terminal for alternating voltages up to 690 V AC
Description
The EL3783 EtherCAT Terminal is a power monitoring I/O terminal used for state monitoring of a 3-phase AC voltage system. For each phase, voltage up to 400/690 V, eff, and current up to 1 A. 5 A, are sampled as instantaneous values with a resolution of 16 bits. The six channels are measured simultaneously based on the EtherCAT oversampling principle with a temporal resolution of up to 50 µs and then passed on to the control system. The control system has sufficient computing power for true RMS or performance calculations and complex custom algorithms based on the measured voltages and currents. Through the oversampling principle, the terminal is able to measure at significantly shorter intervals than the cycle time of the control system. AC and DC parameters must be connected and measured with a common reference potential.
