RN-101M

RN-101M voltage monitoring relay.

The RN-101M voltage monitoring relay is designed to de-energize an industrial/appliance single-phase 220V/50Hz load in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery.

Besides the relay:

• protect the switched load against high-frequency and high-voltage impulse interference
• limits load current up to 15A (load wattage of up to 3.5kW)
• indicates the circuit RMS voltage

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

• actutal RMS voltage
• accurate value of 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 thresold
• the minimum allowable voltage tripping thresold
• time delay for load re-energizing after the circuit parameters recovery
