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 mounted Benefits Constant monitoring of voltage to detect harmful power line conditions – even before the motor starts Prevents nuisance tripping due to rapidly fluctuating power line conditions Provides diagnostics that can be used for troubleshooting and to determine relay status Allows flexibility in panel installation
