Overview

The GE IS200EACFG3ABB Exciter AC Feedback Board is a critical component in GE’s EX2100 excitation system, part of the Mark VI turbine control platform. This board is responsible for acquiring and conditioning three-phase AC voltage and current signals from the generator. These signals are then transmitted to the control system, enabling real-time regulation of excitation and ensuring consistent generator output under varying load conditions.

Moreover, the EACF board is engineered for long-distance signal transmission and robust field operation. It features differential signal processing and electrical isolation, which enhance measurement accuracy and protect sensitive control electronics. In addition to its core functionality, the board is designed for seamless integration with the EX2100 system, supporting high-reliability applications in power generation.

Therefore, the IS200EACFG3ABB is widely deployed in gas, steam, and hydroelectric power plants where precise excitation feedback is essential for system stability and 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 a load increase 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 and electrical noise.
