More Information

Overview Manuals Optical Link Feedback Delivery Controller Placement Fiber Maintenance

Features:

  • Provides high-speed ISBus communication among M1, M2 and C DSPX controllers.
  • Accepts bridge current and voltage feedback through six front fiber-optic connectors.
  • Supports RS-232C communication with the Toolbox and keypad ports.
The board is a single-slot, 3U module installed below DSPX in the control backplane.

Optical links keep bridge feedback electrically isolated from controller hardware.

Transmit and receive fibers must return to their labeled connector positions after service.

Apter Power handles procurement and available communication-board documentation for the General Electric IS200EISBH1A Exciter ISBus Board for GE EX2100 excitation-control service.

Optical Link for IS200EISBH1A

  • Connector set: Six front connectors accept current and voltage feedback fibers.
  • Signal source: EDCF boards provide generator-field measurement data.
  • Isolation: Fiber optics separate bridge voltage from controller electronics.
  • Direction: Each transmitter and receiver lead must remain on its documented path.

Feedback Delivery for IS200EISBH1A

  • Input: EDCF field-current and field-voltage measurements enter over fiber.
  • Distribution: ISBus exchanges high-speed data among the three DSPX boards.
  • Consumers: Regulation and protection functions use the delivered bridge feedback.
  • Validation: Compare live feedback values with the assigned EDCF channel after replacement.

Controller Placement for IS200EISBH1A

  • Module size: The board occupies one slot and is 3U high.
  • Rack position: It installs in the backplane directly below DSPX.
  • Redundant sections: Equivalent boards support M1, M2 and C controller positions.
  • Backplane role: Backplane connectors carry controller-side communication paths.

Fiber Maintenance for IS200EISBH1A

  • Labeling: Mark connector number and optical direction before removing any fiber.
  • Cleaning: Inspect and clean optical ends without scratching the connector faces.
  • Seating: Reconnect every lead fully in its original front-panel position.
  • Return to service: Verify EDCF feedback and RS-232C access before enabling excitation.
Description
Within the EX2100 control module, the General Electric IS200EISBH1A Exciter ISBus Board links the M1, M2 and C controller sections through the high-speed ISBus. This board occupies the communication layer shared by the three DSPX processors.

Six front fiber connectors bring bridge feedback into IS200EISBH1A. Current and voltage measurements from EDCF travel over isolated optical paths, reducing electrical coupling between the power-conversion hardware and the controller.

RS-232C traffic also passes through IS200EISBH1A between DSPX and the Toolbox and keypad ports. These serial paths are separate from the fiber channels used for bridge measurements.

The single-slot, 3U IS200EISBH1A is mounted directly below DSPX, placing its optical connectors at the front of the control rack while its controller-side interfaces remain on the backplane.

Technical notes
IS200EISBH1A uses directional optical paths. Label all six front connectors before removal and verify EDCF feedback plus RS-232C access after installation.

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.
Why can IS200EISBH1A have power while bridge feedback is missing?
IS200EISBH1A can be powered while a transmit or receive fiber is crossed, loose or assigned to the wrong EDCF channel.
How should six optical leads be moved onto a new IS200EISBH1A?
Label every IS200EISBH1A fiber by connector and direction, then transfer one lead at a time and verify seating.
How can IS200EISBH1A and EDCF faults be separated?
Check the EDCF source, both optical directions and the assigned IS200EISBH1A connector before replacing either board.
Where should IS200EISBH1A sit in the EX2100 control rack?
IS200EISBH1A is a single-slot 3U module installed in the backplane below DSPX.
Why test serial access after replacing IS200EISBH1A?
IS200EISBH1A also links DSPX with Toolbox and keypad RS-232C ports, so serial testing confirms that path was restored.
Does IS200EISBH1A carry only fiber-optic feedback?
No. IS200EISBH1A manages fiber communication and RS-232C links for the Toolbox and keypad interfaces.
What must pass before a new IS200EISBH1A enables excitation?
Confirm all IS200EISBH1A fiber channels, EDCF feedback values and local serial communication before return to service.
