can be provided per motherboard card
rack.

SSR Output Card

•

Opto-isolated feedback sensing of the motor controller M, F/R or H/L contactor coil operating currents
monitors the status of the SSR condition. During operation, or upon start-up, if the SSR output in any of
the monitored circuits is detected to be shorted, or open, the radio receiver will shut down the motor
controller.

•

Additional SSR modules can be optionally configured to monitor an unused auxiliary contact mounted on
the motor controller M, F/R or H/L contactors to provide positive indication the contactor has picked up
when commanded.
