The IS200EISBH1A is built as an Exciter ISBus card. This is a communication interface board for the M1, M2/C controllers. It provides communication between three DSPX boards that are placed (one each) in M1, M2, and C. This is a single-slot, 3U high module. It receives and transmits feedback signals through its backplane connectors.
The IS200EISBH1A is built with a faceplate that carries several components. This faceplate includes the manufacturer’s logo, the board id number, and an opening to reach a reset switch located on the surface of the circuit board. There are also six openings that are populated by the following fiber optic connectors: under Gen Field, both voltage and current; under Exciter, both voltage and current; under Gnd Detect, in and out.
