Product Introduction
In utility-scale power generation, regulating generator rotor excitation and field current demands high-speed analog processing and fault isolation. The GE IS200ERIOH1A functions as an Exciter Regulator Input/Output (ERIO) board within GE EX2100 excitation control systems.
Mounted in the main control rack, this module acquires line voltage feedback, field current transducer signals, and customer contact inputs, converting them for the system’s DSP controller cards. Replacing a degraded ERIO card with a factory-tested unit resolves generator voltage hunting, loss-of-excitation fault trips, and backplane communication alarms during forced power plant outages.
