FUNCTIONAL DESCRIPTION:

IS200EISBH1AAB is an Exciter ISBus Board manufactured and designed by General Electric as part of the EX2100 Series used in the GE Excitation Turbine Control Systems. The Exciter ISBus Board (EISB) is a special communication board for the M1, M2, and C controllers. It receives and transmits fiber-optic feedback signals and transmits them over the control backplane to the DSPX controller and also communicates between the DSPX and the tool and keypad ports using RS-232C through the backbone connector. In addition, for redundant exciters, EISB contains ISBus interface electronics. ISBus is a GE proprietary communications interface, used here to transfer data among the exciter's M1, M2, and C controllers. EISB is a single-slot, 3U-high module in the control rack under the DSPX. From fiber-optic connectors on the front panel, it accepts current and voltage signals from the generator field (and from the Exciter if required) using EDCF boards. It receives and transmits signals to the Ground Detection module.

OPERATION:

• Data Transmission and Communication: The board ensures high-speed data exchange between the excitation system and connected control systems, such as the turbine's main controller or other subsystems. It supports industrial communication protocols like Modbus or Ethernet to maintain efficient and reliable operations, facilitating the exchange of commands, status updates, and performance metrics.

• Signal Processing: Incoming signals from sensors, controllers, or supervisory systems are processed by the board. It interprets these signals, converts them into actionable data, and forwards them to the relevant system components. This ensures that all parts of the excitation system function in harmony.

• Fault Detection and Diagnostics: The board continuously monitors the system for any irregularities or faults. When an issue is detected, it generates alerts and logs diagnostic information, enabling operators to address the problem quickly and minimize downtime. This proactive approach enhances system reliability and reduces the risk of equipment failure.

• Control and Command Execution: Commands from higher-level control systems are transmitted through the Exciter ISBus Board to execute specific operations, such as adjusting the excitation current, managing voltage levels, or responding to load changes. This real-time command execution ensures optimal performance and stability of the generator.

CONNECTORS:

The board front panel has six fiber optic connectors for receiving and transmitting variable frequency signals as follows:

• Generator field DC Voltage input from the EDCF board
• Generator Field DC input from the EDCF board
• Exciter Voltage input from EDCF (optional)
• Exciter current input for EDCF (optional)
• Ground Detector Voltage input
• Ground Detector Voltage output
