GE IS200ECTBG1A Exciter Contact Terminal Board

GE IS200ECTBG1A Exciter Contact Terminal Board

Functional Description

The IS200ECTB1A terminal board supports excitation contact outputs and inputs in the EX2100 Excitation

Control. There are two versions; the ECTBG1 board is only used in the redundant control, and the ECTBG2

board is only used in the simplex control. Each board contains two trip outputs driving a customer lockout,

controlled by the EMIO board. There are also four general purpose Form-C contact outputs controlled by the

EMIO board. 

Six auxiliary contact inputs are powered (wetted) with 70 V dc and monitored by ECTB. Also, the 52G and 86

G contact inputs are powered with 70 V dc and monitored. In the redundant control, power comes from both

the M1 and M2 controllers.
