IS200EISBH1A - Exciter ISBus Board

Functional Description

IS200EISBH1A is an Exciter ISBus Board manufactured and designed by General Electric as part of the EX2100 series used in GE Excitation Control Systems. The Exciter ISBus Board (EISB) is a specialized communication board designed for the M1, M2, and C controllers. It handles the reception and transmission of fiber-optic feedback signals, forwarding these signals via the control backplane to the DSPX controller. Additionally, it facilitates communication between the DSPX and tool/keypad ports using RS-232C through the backbone connector. For setups with redundant exciters, the EISB incorporates ISBus interface electronics. ISBus, a proprietary GE communication interface, is used here to exchange data among the M1, M2, and C controllers of the exciter system. The EISB is a single-slot, 3U-high module situated in the control rack beneath the DSPX. Its front panel features fiber-optic connectors that receive current and voltage signals from the generator field (and optionally from the Exciter) via EDCF boards and also transmit signals to the Ground Detection module.

APPLICATION DATA:
The front panel of the board is equipped with six fiber optic connectors designed for receiving and transmitting variable frequency signals, which include:

• DC voltage input from the Generator Field via the EDCF board
• DC input from the Generator Field via the EDCF board
• Optional voltage input from the Exciter via the EDCF board
• Optional current input from the Exciter via the EDCF board
• Voltage input to the Ground Detector
• Voltage output from the Ground Detector
