Used as either a standalone Electronic Motor Protection Relay or as part of an automation network process communicating to a PLC, this motor control relay is equipped with 5 digital inputs accepting field supply voltages from 24V to 220V AC or DC and 4 potential free C/O contacts, 2 of which are programmable.
Thermal curves (Class 3 to 35), to IEC 60255-8, 3 x PTC 100 inputs, earth leakage, earth fault and short circuit protection, load loss protection, over and undervoltage protection and voltage symmetry are all features available through the range 5 to 250A.
The integrated C.T. block also includes the earth leakage core balance C.T. Indication LEDs address the need of maintenance personnel involved in fault-finding, while the free NewElec frontend software enables recording of the motor performance.
WHY WAIT TO AUTOMATE?
Ideally suited for economically converting an old plant to an automated one at substantially reduced costs by using existing control voltages that are simply adapted for the MA Relay which then communicates to a PLC/DCS via Profibus DP, Modbus RTU or Canbus.
