More Information

Overview Manuals AC Feedback Path Voltage Inputs Coil Inputs Controller Outputs

Features:

  • Measures EX2100 bridge AC supply voltage and current feedback.
  • Uses transformer-isolated three-phase voltage inputs and two coil channels.
  • Fans conditioned signals out to the M1, M2 and C controllers.
The G3 board is selected for the high-voltage PPT input class and converts the three phases into low-level measurement signals.

Separate coil terminals carry the two current-feedback sources, with shielding and noise suppression placed near the entry point.

Three DB9 cable paths let the same conditioned feedback reach each control section without routing raw bridge signals into the control enclosure.

Check the G3 voltage class, terminal assignments and controller-cable routes when pairing General Electric IS200EACFG3A with an EX2100 feedback circuit.
General Electric IS200EACFG3A Exciter AC Feedback Board Manuals,Datasheets,Link Important Notice: Confirm the G3 voltage version, PPT phase order and M1/M2/C output assignments before using the feedback details.

From bridge measurements to control sections

  • Source: The board receives PPT ac supply voltage and current signals.
  • Conditioning: Voltage transformers reduce the three-phase feedback level.
  • Distribution: Conditioned circuits fan out through three controller connectors.
  • Cabinet Layout: The terminal board remains in the exciter auxiliary cabinet.

Three-phase PPT terminal organization

  • Phase A: TB1 terminates the phase-A PPT input.
  • Phase B: TB2 accepts the phase-B connection.
  • Phase C: TB3 completes the three-phase measurement set.
  • Test Rings: TP1-TP4 expose defined phase-to-phase transformed outputs.

Flux/Air current-feedback channels

  • Channel One: TB4 terminals 1 and 2 connect the first Flux/Air core coil.
  • Channel Two: TB4 terminals 3 and 4 connect the second coil.
  • Noise Control: High-frequency suppression is placed near the signal entry.
  • Shielding: Adjacent shield screws reference applicable cable shields to chassis ground.

Separate feedback paths for M1, M2 and C

  • M1 Path: J504 carries feedback toward controller M1.
  • M2 Path: J509 provides the second controller cable interface.
  • C Path: J514 serves the C control section.
  • Cable Reach: The interface cable to the backplane can extend up to 90 m.
Description
For bridge-feedback measurement in an EX2100 system, General Electric IS200EACFG3A acts as the Exciter AC Feedback terminal board. It receives the exciter PPT ac supply voltage and current signals in the auxiliary cabinet and conditions them for the control sections.

Three phase inputs enter IS200EACFG3A at TB1, TB2 and TB3. Onboard potential transformers reduce the bridge voltage to low-level feedback, and TP1-TP4 provide defined phase-to-phase measurement points for the transformed outputs.

Two Flux/Air core coils connect through TB4 so IS200EACFG3A can carry the corresponding current-feedback channels. High-frequency noise suppression is located close to these inputs, with nearby shield terminals tied to chassis ground.

Conditioned voltage and current signals leave IS200EACFG3A through J504, J509 and J514 for controllers M1, M2 and C. The feedback cables to the control backplane may extend to 90 m, allowing the EACF board to remain in the exciter auxiliary cabinet.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can a technician confirm the phase order on IS200EACFG3A?
Trace the three PPT phases to IS200EACFG3A terminals TB1, TB2 and TB3, then use the defined TP1-TP4 pairings to check the transformed line-voltage outputs.
Which detail prevents the wrong voltage version from being selected for IS200EACFG3A?
Verify the G3 group in the complete IS200EACFG3A number and compare its voltage class with the installed PPT feedback circuit.
Where should the two current-sensing coils land on IS200EACFG3A?
Both Flux/Air core coils terminate at IS200EACFG3A TB4: terminals 1-2 form the first channel and 3-4 form the second.
What matters when routing long feedback cables from IS200EACFG3A?
Keep the IS200EACFG3A cable assignment consistent for J504, J509 and J514, preserve the shield connection, and remain within the 90 m backplane-cable limit.
Why are three output connectors fitted to IS200EACFG3A?
IS200EACFG3A fans the conditioned voltage and current feedback to the M1, M2 and C controller sections through separate DB9 paths.
