About the IS200EACFG1B

The IS200EACFG1B model is an exciter alternating current feedback board, which controls the incoming potential power transformer (PPT) voltages as well as air core current transformer signals. The currents that go through the EACF board are sent to three DB9 connectors which are the cable to controllers connected to M1, M2, and C. The cable shield terminal screws that are needed to attach the exciter feedback board are located on the frame within three inches of the other input screws. 

There are also two terminals located on the board which are used for two flux/air core coils. The IS200EACFG1B model is used with an exciter backplane board (EBKP), which is the controller between the two boards. There are no LED indicators or displays on this controller which is why the IS200EACFG1B must be connected to an EBKP model such as the IS200EBKPG1B model. 

Frequently Asked Questions about IS200EACFG1B

What are the voltage test rings on the IS200EACFG1B board used for?

The voltage rings are used to measure the phase voltage output from potential transformers they do so as follows: between TP4 and TP1, obtain phase-to-phase voltage CA, between TP1 and TP2 obtain phase-to-phase voltage AB, and between TP3 and TP4 obtain phase-to-phase voltage BC.

Does the IS200EACFG1B have a different functional revision than the IS200EACFG1A model?

Other than the functional revision letters being different there appear to be no differences between this model and its predecessor. The GEI-100465A Exciter AC Feedback Board User's Guide provides more information on the IS200EACF boards. 

What type of board is the IS200EACFG1B model?

The IS200EACFG1B board is an Input-Output Terminal Board and will handle all bridge AC voltages and current feedback. 

How are the different voltages and circuits fanned out on the IS200EACFG1B board?

The different voltages and circuits accepted by the IS200EACFG1B board are fanned out to three DB9 connectors for cables to controllers M2, M1, and C.
