IS200EPCTG1A - EPCT Exciter PT/CT Board | GE EX2100 | B7B

IS200EPCTG1A is a General Electric EPCT Exciter PT/CT Board for GE EX2100 excitation control systems. In the EX2100 control cabinet, the EPCT terminal board wires generator potential transformer (PT) and current transformer (CT) feedback signals to the EMIO board for use by the excitation regulator.

The GEH-6632G EX2100 user guide describes the EPCT as providing two 3-phase PT voltage inputs (10-200 V rms, 115 V rms nominal), two CT current inputs (0-1 A rms or 0-5 A rms), and one selectable 0-10 V or 4-20 mA analog input, with non-pluggable CT terminal blocks TB2/TB3 using ring terminals; redundant systems fan signals to M1, M2, and C. For maintenance, repair, and spare-part planning, IS200EPCTG1A 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.
