Product: IS200ECTBG1ADA IS200ECTBG1ADE GE Exciter Contact Terminal Board
Description
The ECTB board supports excitation contact outputs and contact inputs.
There are two versions: the ECTBG1 board which is only used in the redundant mode, and the ECTBG2 board which is only used in the simplex mode.
Each board contains two trip contact outputs driving a customer lockout, and four general purpose Form-C relay contact outputs, controlled by the EMIO board.
Six auxiliary contact inputs are powered (wetted) with 70 V dc by ECTB. Also, the 52G and 86 G contact inputs are powered and monitored by ECTB.
In the redundant case, power comes from the M1and M2 power supplies.
ECTB provides four general purpose Form C contact outputs controlled by EMIO.These are used for 94EX and 30EX and other outputs. For each relay, the coil current and the status of a relay auxiliary contact is monitored.
These feedbacks are cabled to EMIO in the controller.
ECTBG1 is the redundant control version of the ECTB. This fans inputs to three connectors J405, J408, and J418 that are cabled to the three controllers. For relay control, the board does two-out-of three voting, and the 70 V dc and 24 V dc inputs are redundant.
