Description
🔹 Product Description
The GE IS200ECTBG2A is an Exciter Contact Terminal Board (ECTB) designed for the GE EX2100 Excitation Control System. This G2 version is intended for simplex-mode operation and provides an interface for excitation-related contact inputs and outputs. The board works with the EX2100 EMIO interface and handles auxiliary contact monitoring, trip contact outputs, and general-purpose Form-C relay outputs. The board supports six auxiliary contact inputs, two trip contact outputs, and four Form-C relay contact outputs. It also provides contact wetting using approximately 70 VDC within the EX2100 contact interface architecture. The related full assembly designation IS200ECTBG2ADE should be checked against the installed system documentation before replacement.
