RN-111M single phase 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
