Product Overview
IS200EDEXG1BQ is a high-performance de-excitation bridge and protection board designed by GE for the EX2100 Excitation Control Series.
This module manages generator field discharge and protection functions during shutdown or fault conditions.
The board supports fast de-excitation control using an SCR-based discharge path.
It works together with the EMIO and EXTB boards for stable excitation system operation.
The EXTB board supplies power and control signals during standard operation.
The EDEX board can still trigger de-excitation if EXTB control fails.
24 VDC power input supports reliable field discharge control.
The SCR circuit quickly removes stored magnetic energy from the generator field.
This process protects connected equipment from overvoltage damage.
The module includes break-over diode protection for emergency SCR triggering.
Its rugged design fits demanding industrial power environments.
