ICM441

Details Specifications Install Guide Replaces
Motor Temperature Controller
The ICM441 is designed to individually monitor 3 PTC temperature sensors which are wound into each phase winding of a motor. If any winding or incoming line power is beyond the safe operating range of the motor, the ICM441 will lock the motor out of operation until the inputs fall back into the safe operating range. The ICM441 can sense shorted or open sensors, in addition to providing isolation to each sensor to prevent damage to the monitor in the event a sensor shorts to a winding or case ground.
