A power circuit breaker control indicator module (CIM) features a built-in serial link that monitors up to three breaker trip coils.
The unit enables a utility to control and monitor single, dual, or triple coils for integrity while providing a local manual failsafe switch. Combining multiple functions in a single device that uses less than 13 sq in. of panel space, the device can go online with up to 32 separate computer workstations, printers, or other peripherals. Time stamping provides a precise record of recent events. The unit trips and closes a circuit breaker through one of three methods: from a manual control switch mounted on its front panel, a signal from any protective relay device, or a remote signal through its interface with SCADA. Two toggle switches on the front panel also allow manual control of the automatic reclose function and the SCADA connection. The RS485 interface allows the use of DNP 3.0, Modbus, and other compatible communications protocols.
