Signal Routing & Interface

The IS200EMIOH1ACA connects to the EBKP control backplane via P1 and P2 connectors. P1 handles communication with other control boards, while P2 routes I/O signals from terminal boards. It sends logic-level gate pulses to the ESEL board, which relays them to EGPA in the power conversion cabinet.

Application & Compatibility

This board supports high-speed signal processing and integrates seamlessly with GE EX2100 excitation systems. It provides reliable I/O management for generator protection, control logic, and relay actuation. The absence of jumpers or fuses simplifies installation and maintenance.
