The EL3443-0020 EtherCAT Terminal enables the measurement of all relevant electrical data of the supply network and carries out simple pre-evaluation. The voltage is measured via direct connection of L1, L2, L3 and N. The current of the three phases L1, L2 and L3 is fed via simple current transformers. All measured currents and voltages are available as root-mean-square values. In the EL3443-0020 terminal, the effective power and energy consumption for each phase are calculated. The RMS values of voltage U and current I as well as the active power P, apparent power S, reactive power Q, frequency f, phase shift angle cos φ and harmonic are available. The EL3443-0020 offers extended functionality for mains analysis and energy management.

In addition, the EL3443-0020 comes with the option of transmitting the time of the last voltage zero crossing to the controller via XFC technology. This can be used, for example, to carry out switching operations to suit the application.

The EL3443-0020 can be ordered for other current ranges, such as 5 A, 100 mA or 333 mV. An overview of the different versions can be found under ordering information.

The individual Beckhoff factory calibration certificate can be downloaded here for each device. Recalibration (ZS9001) is possible via Beckhoff Service.
