EL3453

EL3453 is a Beckhoff measurement terminal in the EL EtherCAT Terminals series. Its EtherCAT network interface provides communication with an EtherCAT control system, while distributed-clock support enables synchronized measurement timing across network devices. The transformer-coupled connection type supports measurements through external current transformers.

The terminal measures three-phase electrical systems and includes three voltage inputs and three current inputs, providing one voltage and current measurement channel for each phase. It supports a nominal voltage of 690 V AC and nominal current ratings of 1 A AC or 5 A AC for use with compatible measurement circuits. The True RMS measuring method calculates effective values for both sinusoidal and distorted waveforms. Measurement through the 40th harmonic enables analysis of waveform components up to that harmonic order.

The housing is 24 mm wide. Its IP20 protection rating provides protection against finger contact and solid objects larger than 12.5 mm, but it does not provide water protection.
