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.
