IS200EDEXG1ADA Exciter De-Excitation Control Board
The IS200EDEXG1ADA Exciter De-Excitation control board (EDEX) is the main board in the de-excitation module. This module removes stored energy from the generator field when an emergency shutdown occurs and the field breaker or contactors open. EDEX provides SCR firing, conduction sense feedback, and voltage retention to ensure operation in the event of a power failure.
EMIO initiates de-excitation on the EXTB board. The EXTB board opens the 41dc contactor (MDA/MDB) or breaker, and then transfers de-excitation signals from the auxiliary contacts to SCR firing circuits on the EDEX.
There are two types of EDEX board. Group 1 is designed for SCR de-excitation, and Group 2 is designed for diode de-excitation.
