The GE IS200ERBPG1ACA Input/Output (I/O) Interface Module serves as a critical interface between
the EX2100 excitation control system's backplane and external field devices, enabling bidirectional
signal exchange through terminal boards. It processes and conditions analog inputs (PT/CT signals, 4–
20 mA), discrete inputs (status contacts), and generates precise analog outputs (±10 V, 4–20 mA) and
relay outputs for control actions. The module incorporates signal conditioning, isolation (typically 2.5
kV AC), and surge protection to ensure reliable operation in high-EMI environments. It communicates
with the DSPX controller via the EISB bus, providing real-time diagnostics and enabling hot-swap
capability in redundant configurations. The module is designed for single-slot 3U Eurocard mounting
in EX2100 racks, with LED indicators for quick status assessment, conformal coating for environmental
resilience, and compatibility with standard EX2100 terminal boards.
