Overview
The IS200EDEXG1BAA Exciter De-Excitation Control Board is a critical safety component in GE’s EX2100e excitation platform. It actively manages the controlled dissipation of excitation current when the generator field breaker or contactors open. This fast-response action prevents overspeed and electrical stress, ensuring safe transitions during shutdowns, trips, or fault conditions.
Moreover, the EDEX board is engineered for high reliability and seamless integration with other EX2100e modules. It features configurable jumpers for flexible setup and supports diagnostic feedback for maintenance and fault analysis. In addition to its core function, the board contributes to system stability and compliance with protection standards in high-voltage environments.
Therefore, this module is widely used in gas, steam, and hydroelectric power plants where precise de-excitation is essential for generator safety and operational continuity.

Typical Applications
-
Generator Excitation Systems: Ensures safe shutdown by rapidly dissipating field current.
-
Power Plant Protection: Prevents overspeed and voltage surges during fault conditions.
-
EX2100e Cabinets: Integrated into excitation racks for coordinated control.
-
Industrial Generator Control: Used in petrochemical, mining, and manufacturing sectors.
-
System Retrofits: Compatible with legacy GE Mark VI installations for modernization.
For example, during a turbine trip, the EDEX board activates to discharge excitation energy, helping the generator decelerate safely. In addition, its compact design and fast response make it ideal for high-density control environments.
