Power monitoring relay PQRM5100 31 series

three-phaseDIN railRS485

The PQRM5100 31 … Three phase multifunction Power Transmitter suitable for the measuring of 51 different parameters of the three phase power network: • the TRMS values of phase voltages and phase currents • active power, reactive power, apparent power and power factor per each phase • +active energy, -active energy, inductive energy, capacitive energy per each phase and per 3 phase • frequency, phase angle, line voltages, phase angles between phase voltages. • The voltage inputs of the equipment are resistor networks (nonisolated) and the current inputs are isolated from the network with wideband current transformers. The current inputs 0-5 AAC or 0-1 AAC, and the voltage inputs 0-125 VAC / 0-250 VAC are in compliance with the requirements for measurement category CAT III. The PQRM5100 31… is available with the following output options: • 2 × 0-20 mA / 4-20 mA galvanic isolated, scalable, active analog current outputs * • MODBUS RTU galvanic isolated communicatoin which makes possible the reading of all measurement values via the communication line, with a PLC or with a PC *. • 2 energy pulse outputs / limit outputs for limit-switching and for simple control tasks. The measurement and output parameters are configurable from PC via USB port with the help of a user friendly configuration software. The configuration software is free of charge. The PQRM5100 31 … has two power supply versions 19-35 VAC / 25-50 VDC (PQRM5100 31 …) or 90-250 V AC/DC (PQRM5100 31 … PS).
