Description

The 201-xxx-DPDT Series is an 11-pin octal base plug-in voltage monitor designed to protect 3-phase motors regardless of size. The 201-100-DPDT is used on 95–120 V ac, 50/60 Hz motors and the 201-200-DPDT is used on 190–240 V ac, 50/60 Hz motors to prevent damage caused by incoming voltage problems. The units feature two isolated sets of contacts that are ideal for use with two control circuits with different voltages. The unique microcontroller-based voltage and phase-sensing circuit constantly monitors the voltages 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. This unit is also available with a shorter trip delay and faster restart delay. The 201-xxx-DPDT -60mS has a trip delay of 0.5 seconds and a restart delay of 60 milliseconds. Features & Benefits FEATURES BENEFITS Proprietary microcontroller based circuitry Constantly monitors 3 phase voltage to protect against harmful line conditions, even before the motor is started Compact design for 11-pin; DIN rail or surface mount Allows flexibility in panel installation Advanced LED indication Provides diagnostics which can be used for troubleshooting and to determine relay status T wo isolated Form C relays (DPDT) Ideal for use in systems which have two control circuits with different voltages Accessories OT11PC Octal Socket 11-pin surface & DIN rail mountable. Rated for 10 A @ 300 V ac. 3-phase voltage/phase monitor 201-XXX-DPDT SERIES Wiring Diagram STOP 67 7 INPUT POWER L1L2L3 LIGHT CONTROL POWER CONTROL POWER HORN
