The GE IS200EISBH1AAA Exciter ISBus Board (often abbreviated as EISB) is a specialized communication interface board manufactured by General Electric for use in their EX2100 Series Excitation Control Systems and as part of the Mark VI Speedtronic family of turbine control systems.
🛠️ Primary Function
The board’s main role is to facilitate high-speed communication and data exchange within the exciter control system.
- Communication Interface: It acts as a bridge between the M1, M2, and C controllers (main control modules).
- Data Transmission: It receives and transmits fiber-optic feedback signals from the generator field and, optionally, the exciter, using EDCF boards.
- DSPX Link: It sends these fiber-optic signals over the control backplane to the DSPX controller (Digital Signal Processor).
- ISBus: It incorporates the proprietary GE ISBus interface electronics for transferring data, which is essential for coordination, especially in redundant exciter setups.
