A microprocessor-based control module for Allen-Bradley Bulletin 1502 medium-voltage vacuum contactors installed in Bulletin 1500 and 1900 CENTERLINE motor controllers. It manages contactor pick-up, hold operation, controlled drop-out and operating status.

Controls the coil circuit while monitoring command, power and contactor conditions.

Inside the Control Module

The module combines command processing, coil control, timing and status supervision in one enclosure.

Start, stop and latch request enters through the control circuit.

BMC4 evaluates power, mode, timing and command conditions.

Pick-up energy, hold operation and drop-out timing are coordinated.

The 1502 mechanism moves and auxiliary state returns to the control system.
