Technical Datasheet (PDF)

The RN-111M voltage monitoring relay is designed to de-energize an industrial/appliance single phase 220 - 240V/50Hz load in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery. Load is connected to the relay either directly via relay terminals or through a magnetic contactor, depending on the wattage.

The relay can operate in four independent modes:

  • Maximum and Minimum Voltage monitoring relay
  • Minimum voltage monitoring relay
  • Maximum voltage monitoring relay
  • Time relay with a restart delay

The device front panel features load status indicator (on/off) and three-digit, seven-segment display, which displays (depending on the device status):

  • Actual RMS voltage
  • Accurate value of the set-up parameter
  • Time remaining till automatic load re-energizing
  • Emergency de-energizing the load (RMS voltage flashing)

The variable pot knobs on the front panel allow for setting:

  • The maximum allowable voltage tripping threshold
  • The minimum allowable voltage tripping threshold
  • Time delay for load re-energizing after the circuit parameters recoveryest
