IS200EACFG2ABB GE Exciter AC Feedback Board for Generator Systems

Description

The GE IS200EACFG2ABB Exciter AC Feedback Board is a critical component in the EX2100 excitation system, part of GE’s Mark VI turbine control platform. Its primary function is to measure and condition three-phase AC signals from potential transformers (PTs) and current transformers (CTs), delivering accurate feedback to the controller for real-time regulation of generator excitation. Moreover, the board supports differential signal processing and electrical isolation, ensuring high signal fidelity and system safety. In addition to its measurement capabilities, it features three DB9 connectors that interface with control processors (M1, M2, and C), enabling redundant and fault-tolerant operation. Its rugged design allows installation in harsh industrial environments, including high-temperature and high-vibration zones. Therefore, the IS200EACFG2ABB is widely used in power generation systems where precise excitation control is essential for maintaining voltage stability, reactive power balance, and generator protection.
