Description
The GE General Electric IS200EISBH1A, identified by the full part number IS200EISBH1AAC, is an Exciter ISBus Board designed for GE Mark VI turbine control and EX2100 excitation control systems. The EISB provides an interface for ISBus communication and manages fiber-optic feedback signals within the excitation system. It is a single-slot, 3U-high board designed for VME rack installation, with fiber-optic connections for generator field voltage/current, exciter voltage/current, and ground-detection signals. The board also includes a reset switch, backplane interface, integrated signal-conditioning circuitry, and conformal-coated PCB construction.

Safety & Troubleshooting
• Disconnect and isolate excitation-control power before removing or installing the board.
• Verify the complete part number and revision before replacement.
• Inspect fiber-optic connectors for contamination, damage, or improper seating.
• Check the backplane connector and rack seating if communication faults occur.
• Verify generator-field, exciter-feedback, and ground-detection connections against the original installation.
• Check the board reset condition and associated controller diagnostics when the EISB is not communicating correctly.
• Do not disconnect or reconnect fiber-optic or electrical connections while the system is energized unless the applicable GE maintenance procedure specifically permits it.
• Follow the site-specific excitation-system maintenance and commissioning procedures before returning the system to service.
