Product Description

The Exciter AC Feedback Board IS200EACFG3A is the final of the three G versions of the IS200EACF board. The G3 version of this module can handle an input voltage of up to 1300 VRMS. The transformers on this model typically supply a nominal of 1.6 VRMS. The IS20EACFG3A module has four voltage test rings labeled TP1, TP2, TP3, and TP4. Normally these four voltage rings are paired together and measure the phase voltage outputs; together TP1 and TP2 obtain the Line voltage AB, TP3 and TP4 obtain the Line voltage BC, and TP4 and TP1 obtain the Line voltage CA.

The IS200EACFG3A model has three screw terminals, TB1, TB2, and TB3 all have different signals that they are used for, the three are each connected to potential phase transformers. TB1 is connected to PPT phase A, TB2 is connected to PPT phase B, and TB3 is connected to PPT phase C.

Frequently Asked Questions about IS200EACFG3A

How does the G3 version of the EACF boards operate?

Version G3 of the IS200EACFG3A boards operates on a nominal range of 1300 VRMS compared to 480 VRMS for the G1 version and 1000 VRMS for the G2 version.

What does each transformer/terminal on the IS200EACFG3A board indicate?

Transformers T1 through T4 are three-phase voltage transformers. The TB1, TB2, and TB3 terminals are used for voltage inputs, and terminal block TB4 is used for wiring from the Flux/Air coils.

Is the IS200EACFG3A connected to any other boards within the EX2100 Series?

Yes, the IS200EACFG3A board is connected to the EMIO board which manages the I/O voltages.

What is the best and easiest way to replace the IS200EACFG3A board if it no longer works?

Ensure that power to the auxiliary cabinet is completely off prior to beginning to remove the IS200EACFG3A board, once verified that the power is off carefully disconnect all of the cables; when removing cables be sure that they are all labeled to allow for quicker and easier reconnection when putting in the new board. Once the new board is received put it where the old board resided and start the power after all cables have been reconnected.
