Overview
IOMod 4Cs4Vs is a stand-alone analog inputs measurement module for voltages and currents based on sensor technology with communication support based on Modbus RTU, IEC 60870-5-101, and IEC 60870-5-103 protocols. Designed to measure voltage and current values with high accuracy in real time. IOMod 4Cs4Vs can be used for numerous applications like electrical distribution substations, gas distribution substations, photovoltaic and hydropower plants, and railway power supplies where the user needs them. IOMod 4Cs4Vs calculates neutral current and voltage RMS values I0 and U0 as well as many other measurements like active, reactive, apparent power for every phase, power factors per phase, phase angles for currents and voltages, and harmonics.
