Overview

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.

Technical Data

Typical Applications

• Generator Excitation Control: Provides real-time AC feedback for voltage regulation and reactive power control.

• Power Plant Automation: Interfaces with EX2100 controllers to maintain generator stability and performance.

• Protective Relay Systems: Supplies accurate voltage and current data for fault detection and isolation.

• Industrial Generator Monitoring: Used in petrochemical, mining, and manufacturing facilities for excitation feedback.

• System Upgrades and Retrofits: Compatible with legacy Mark VI installations for enhanced control precision.

For instance, during load changes in a steam turbine generator, the EACF board ensures the excitation system adjusts field current to maintain voltage stability. In addition, its isolated signal paths protect control electronics from transient faults.
