GE IS200EACFG1B Exciter AC Feedback Board

GE IS200EACFG1B Exciter AC Feedback Board

Functional Description

The IS200EACFG1B Exciter Ac Feedback board (EACF) measures the exciter PPT ac supply voltage and current

in the EX2100 Excitation Control. The terminal board contains transformers for a three-phase voltage

measurement, and terminals for two Flux/Air core coils. The outputs of the voltage and current circuits are

fanned out to three DB9 connectors for cables to controllers M1, M2, and C. The cable between EACF and

the EBKP backplane board can be up to 90 m in length. 

The EACF board is located in the exciter auxiliary cabinet. 

There are three versions of the board, EACFG1 for inputs up to 480 V rms, EACFG2 for inputs up to 1000 V

rms, and EACFG3 for inputs up to 1300 V rms. Revision EACFG3BAA and later are rated for inputs up to 1400

V rms.

High frequency noise suppression near the point of signal entry is provided for the flux/air core input signals.

Cable shield terminal screws attached to chassis ground are located within three inches of the input screws

where applicable.
