IS200EISBH1A - EISB Exciter ISBus Board | GE EX2100 | B7B

IS200EISBH1A is a General Electric EISB Exciter ISBus Board for GE EX2100 excitation control systems. In the EX2100 control module, the EISB board provides the ISBus communication path between the DSPX controller, toolbox, and keypad, and receives fiber-optic feedback signals from the EDCF board.

The GEH-6632G EX2100 user guide describes the EISB as a single-slot, 3U module located below DSPX, with six fiber-optic connectors on the front of the cabinet, RS-232C toolbox/keypad communication, and support for the M1, M2/C controllers. For maintenance, repair, and spare-part planning, IS200EISBH1A is an important replacement communication board when supporting EX2100 excitation control cabinets, redundant or simplex control architectures, and turbine-generator excitation system reliability.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
