GE IS200ERIOH1AAA Exciter Regulator I/O Board Mark VI EX2100

GE IS200ERIOH1AAA is the Exciter Regulator I/O (ERIO) board developed for GE Mark VI Speedtronic turbine control and EX2100 digital excitation system. It serves as the discrete signal interface between the excitation controller and field devices, collecting digital input status and driving relay outputs for excitation interlock and protection logic.

This board comes with 16 configurable digital input channels and 16 relay output points. It communicates with DSP and EROC boards via VME backplane bus, with on-board status LEDs for fast fault inspection. It is widely used as spare replacement parts for power plant generator excitation cabinet maintenance and retrofit projects.
