Product Detail

GE IS200EDEXG1B EXCITER DE-EXCITATION BOARD
Description:

IS200EDEXG1B is designed as GE EX2100 Excitation Control system card. IS200EDEXG1B is a Exciter De-Excitation board. IS200EDEXG1B provides de-excitation 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 41 dc contactor (41A/41B) 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. Group 1 board is designed for SCR deexcitation, Group 2 is designed for diode de-excitation.

IS200EDEXG1B contains Hall effect conduction sensors. The sensors are mounted in the air gap of a circular steel core attached to the board. They sense the magnetic field produced by the field discharge current flowing through the thyristor. Two independent sensor circuits are used. The EDEX fires the SCR when either of two control inputs is true or when the anode to cathode voltage of the SCR exceeds a certain value. The two firing control circuits on the board are powered from separate power supplies and use separate conduction sensors making them mutually independent.
