GE EX2100 Exciter Main I/O Board IS200EMIOH1A

Core Functionality & System Integration

• The IS200EMIOH1A serves as the central I/O management hub within the EX2100 control system.
• This General Electric board processes signals from multiple terminal boards including ECTB, EACF, EXTB, and EPCT.
• It handles critical tasks like contact input monitoring and output relay driving for system control.
• The board also generates and sends logic-level gate pulse signals to the ESEL board via the backplane.
• Its operation initiates de-excitation sequences by controlling the connected EDEX board.

Expert Technical Support & FAQs

• What is the primary function of the Status LED on the EMIO board?
• The Status LED connects directly to the FPGA's IMOK output, providing real-time board health status.
• How does the EMIO board interface with other system components?
• Connector P1 handles backplane communication with other control boards, while P2 interfaces with I/O signals.
• Can the IS200EMIOH1A operate without the EBKP backplane?
• No, all I/O board cabling connects through the EBKP backplane, which is essential for operation.
• What types of signals does this board process for excitation control?
• It handles PT and CT signals, contact inputs, output relay drivers, and pilot trip relay drives.
• Where can I find technical documentation for this board?
• Consult manual GEI-100453 or the GEH-6632 EX2100 User's Guide, page forty-eight for reference.
