Exciter De-Excitation Board | GE IS200EDEXG1BAA for High-Speed Shutdown

Description

TheIS200EDEXG1BAA Exciter De-Excitation Control Boardis a critical safety component in GE’sEX2100e 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, theEDEX boardis 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 ingas,steam, andhydroelectric power plantswhere precise de-excitation is essential for generator safety and operational continuity.
