GE IS200EPCTG1AAA Exciter PT/CT Terminal Board

The GE IS200EPCTG1AAA is a critical Exciter PT/CT Terminal Board in the EX2100 excitation system, handling generator voltage and current measurements via isolation transformers. It integrates two 3-phase PT inputs and two CT inputs, with outputs cabled to the EMIO board.

Supporting up to 1000ft cable lengths, it features fused PT inputs and fixed CT terminal blocks to prevent open circuits. With 12 voltage test points for diagnostics and three 25-pin connectors linking to the EBKP backplane, it enables signal distribution to M1, M2, and C controllers in redundant setups, ensuring reliability. Up to three boards can be used for redundancy, enhancing system robustness.
