Description

General Electric IS200EDEXG1B Technical Overview

The General Electric IS200EDEXG1B is a De-Excitation Bridge and Protection Board (EDEX) designed for the GE EX2100 Excitation Control System within the Innovation Series. Weighing 3 lbs. 6 oz. (1.53 kg), this board is housed in an auxiliary cabinet and interfaces with the EMIO and EXTB control boards. Powered by a 24 VDC supply routed through the EXTB board, the IS200EDEXG1B manages SCR de-excitation and provides backup initiation if primary EXTB control fails, dispersing field energy safely through a field discharge inductor.

Key Features & System Protection

The IS200EDEXG1B operates with a net weight of 3 lbs. 6 oz. and incorporates configurable jumpers JP1 through JP6 for precise hardware setup. Designed with double redundancy, the board initiates field de-excitation if the EXTB control signal fails. In SCR de-excitation mode, the SCR fires to create a conduction path through the field discharge inductor. If normal gate firing fails, an integrated break-over diode string triggers an overvoltage fire sequence when anode-to-gate voltage exceeds break-over thresholds, securing heavy generator field coils against catastrophic fault conditions.
