Functional Description

IS200EDEXG1AEA is an Exciter De-Excitation Control Board developed by GE as part of the EX2100e excitation system. Its primary role is to manage the de-excitation process during emergency shutdowns. When the field breaker or contactors open, the EDEX board initiates SCR (Silicon-Controlled Rectifier) firing to safely dissipate the field energy. By precisely controlling the SCRs, the board ensures a smooth and controlled discharge of current, preventing sudden voltage spikes and maintaining system stability during critical transitions.
