IS200ECTBG1A - ECTB Exciter Contact Terminal Board | GE EX2100 | B7B

IS200ECTBG1A is a General Electric ECTB Exciter Contact Terminal Board for GE EX2100 excitation control systems. In the EX2100 control cabinet, the ECTB terminal board wires customer contact inputs and relay contact outputs to the EMIO board, including trip contact outputs, Form-C relay outputs, auxiliary contact inputs, and 52G/86G status inputs.

The GEH-6632G EX2100 user guide describes the ECTB as providing 2 trip contact outputs, 4 Form-C relay outputs, and 6 auxiliary contact inputs wetted by 70 V dc, cabled to controller EMIO inputs through connectors J405/J408/J418. The G1 revision is the redundant-control version, fanning signals to the M1, M2, and C controllers. For maintenance, repair, and spare-part planning, IS200ECTBG1A is an important replacement terminal 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.
