Product Description:

The EL3413-0000 is a three-phase power-measurement terminal manufactured by Beckhoff for the EL EtherCAT Terminals series. Installed alongside standard digital or analog slices, the unit captures voltages, currents, and derived quantities on each line conductor. Its role in industrial automation is to feed precise electrical data to PLC logic so that energy usage can be optimized, overloads can be detected early, and condition-based maintenance routines can be scheduled without separate stand-alone meters. In doing so, it streamlines energy management tasks across the entire machine.

This terminal accepts phase voltages up to 690 V AC 3~ and line currents up to 5 A AC. A shunt network with an input resistance below 3 mΩ keeps insertion loss minimal, while the current path is digitized with a resolution of 1 µA. Voltage is resolved to 0.1 mV, aided by a 1 MΩ input impedance that limits sensor loading. All three channels are captured simultaneously at 16,800 samples/s; the raw data are condensed into true-RMS values every 200 ms by the onboard DSP. The module performs these calculations with a true RMS procedure, maintaining accuracy even when waveforms are distorted by inverters or other non-linear loads.

For power analysis, the DSP resolves active power in increments of 10 mW with a calculated deviation that stays within 1 %. The combined voltage-and-current accuracy across the full-scale window is 0.5 % FSV, delivering reliable trend data for long-term energy dashboards. Compliance with overvoltage category II permits installation on control-level distribution panels, and the housing carries a protection rating of IP20 for use inside standard cabinets. Together, these attributes enable the controller to perform load profiling and fault detection without adding external transducers.
