Voltage monitoring relay 201-SP-DPDT series

DPDTsingle-phasemotor

The 201-SP-DPDT series is an 8-pin octal base, plug-in voltage monitor designed to protect single-phase motors regardless of their size. The 201-100-SP-DPDT is used on 95–120 V ac, 50/60 Hz motors to prevent damage caused by low voltage. The 201-200-SP-DPDT is used on 190–240 V ac, 50/60 Hz motors. These monitors feature two isolated sets of contacts that are ideal for use with two control circuits with different voltages. The unique microcontroller-based voltage and voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver’s output relays are deactivated after a specified trip delay. The output relays reactivate after power line conditions return to an acceptable level and a specified amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. Notes: Must use Model OT08PC socket for UL Rating Manufacturer’s recommended screw terminal torque for the RB series and OT series octal sockets is 12 in.-lbs. Features Proprietary microcontroller-based circuitry Fixed trip delay 4 seconds Advanced LED diagnostics Compact design for 8-pin; DIN-rail or surface mount
