The IS200EISBH1AAB functions as the dedicated fiber-optic communication hub within the EX2100 excitation system . It utilizes six ST-style optical ports (3 transmitting, 3 receiving) operating with a 3 kHz carrier modulation scheme . By converting analog electrical signals (voltage and current feedback from the generator field) into light pulses, the board achieves complete galvanic isolation, eliminating electromagnetic interference (EMI) from high-power cables.
Within the Mark VI architecture, the IS200EISBH1AAB is the critical interface for the ISBus (Internal Synchronization Bus) . In TMR systems, three identical IS200EISBH1AAB boards work in parallel with the M1, M2, and C controllers. The board continuously exchanges data across these three channels, allowing the system to perform "2oo3" (two-out-of-three) voting on excitation parameters . If one controller or communication path fails, the remaining two healthy channels maintain control without any process interruption.
The IS200EISBH1AAB is built to survive the harsh conditions typical of power generation facilities, such as temperature extremes, humidity, corrosive gases, and vibration . The printed circuit board (PCB) is treated with a specialized conformal coating (lacquer) that protects the sensitive electronics from moisture, dust, and chemical contaminants.The board utilizes high-grade components rated for extended temperature ranges, allowing the IS200EISBH1AAB to function reliably in ambient temperatures spanning from -40°C to +85°C.
The IS200EISBH1AAB GE Communication Board may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Power Generation Plants: Deployed in thermal, gas, steam, and hydroelectric power plants. It ensures accurate generator field excitation and voltage regulation.
- Synchronous Generator Redundancy: Functions in triple-modular redundant (TMR) or dual-redundant control systems to link M1, M2, and C controllers, keeping redundant processors in perfect lock-step.
- Industrial Microgrids & Co-generation: Used in heavy process industries (e.g., steel mills, large petrochemical complexes) where stable, localized grid frequency and voltage regulation are required.
- Fiber-Optic Signal Isolation: Bridges the gap between high-voltage power bridges and low-voltage digital control modules using noise-immune fiber-optic telemetry.
- ISBus Telemetry Diagnostics: Continuously monitors the high-speed internal communication bus (ISBus). It isolates transmission jitter or packet loss before it can cause a controller desynchronization.
- Signal Fault Isolation (EDCF Interface): Collects and validates critical inputs—such as generator field DC voltage, ground detector status, and exciter current—and flags data corruption through hardware-level cyclic redundancy checks (CRC).
- Fiber-Optic Link Quality Monitoring: Tracks light attenuation and transceiver health on the optical ports, issuing preventative diagnostic alarms to the HMI if signal strength drops below operating thresholds.
- Fail-Safe Controller Cross-Checking: If a voting mismatch occurs between the redundant processors (M1/M2), the EISB helps identify which channel is corrupted and assists in a bumpless transfer to the healthy controller, preventing a false system trip.
- Power Down: Isolate all AC/DC power supplies to the control rack. Never hot-swap the board while the excitation system is energized.
- ESD Mitigation: Wear a properly grounded Electrostatic Discharge (ESD) wrist strap attached to the cabinet framework to protect sensitive components on the 3U plug-in architecture.
- Labeling: Document and tag all connected fiber-optic cables and auxiliary wiring prior to removal.
- Card Alignment: Slide the board into its dedicated slot along the chassis guide rails until the backplane connectors align perfectly.
