IS200EACFG3A is an Exciter AC Feedback Board manufactured and designed by General Electric as part of the EX2100 Series used in GE Excitation Control Systems. The exciter PPT ac supply voltage and current are measured by the IS200EACF Exciter Ac Feedback board (EACF). The terminal board comprises terminals for two Flux/Air core coils as well as transformers for three-phase voltage measurement. Three DB9 connectors are used to link the voltage and current circuit outputs to the controllers M1, M2, and C. Up to 90 m of cable can be used to connect the EBKP backplane board to the EACF.

For the flux/air core input signals, high-frequency noise reduction is offered close to the signal entrance point. Where applicable, the input screws are positioned no more than three inches from the cable shield terminal screws connected to the chassis ground.


  • A single three-phase input voltage in the nominal range up to 480 V rms +20% at 50/60 Hz is supported by the G1 version.
  • A single three-phase input voltage in the nominal range of up to 1000 V rms +20% at 50/60 Hz is supported by the G2 version.
  • From their secondary outputs, the potential transformers on both boards deliver a nominal 1.6 V rms.


The image below depicts the EACF board's layout. Three-phase voltage transformers T1 through T4 are used. For the voltage inputs, use TB1, TB2, and TB3 individual screw connectors. The two Flux/Air core coils are wired through terminal block TB4. Cables for the EMIO boards are connected to the EBKP backplane using the three 9-pin sub-D connectors J504, J509, and J514.
