Functional Description
IS200EMIOH1ADA is an Exciter Main I/O Board developed by GE. It is a part of the EX2100 excitation system. It is designed to fit seamlessly within the control rack setup. This single slot, double height VME style board serves as the interface for various terminal boards, including the EPCT, ECTB, EACF, and EXTB. Its primary function revolves around handling a diverse range of input and output signals, encompassing PT (pressure transmitter) and CT (current transformer) signals, contact inputs, output relay drivers, and pilot trip relay drives.
Features
- One of the key functionalities of the board is its ability to transmit logic level gate pulse signals over the backplane to the ESEL board.
- These signals are then forwarded by the ESEL board to the EGPA located in the power conversion cabinet. This communication pathway plays a pivotal role in coordinating and synchronizing critical operations within the control system, ensuring seamless functionality and optimal performance across the entire setup.
- All cabling originating from the various I/O boards is consolidated and connected to the control backplane, denoted as EBKP. This integration ensures a centralized and streamlined approach to managing the intricate network of signals within the control system. Connector P1 facilitates communication between the I/O boards and other control boards by enabling data exchange over the backplane.
- Additionally, connector P2 serves as the interface for transmitting and receiving I/O signals. Positioned at the lower section of EBKP, it accommodates cable connectors that facilitate the seamless integration of I/O signals into the broader control framework. This arrangement optimizes signal transmission and enhances the overall efficiency and functionality of the control system.
Board Replacement Procedure
- Ensure De-Energization: Prior to any work, verify that the exciter has been completely de-energized to prevent any electrical hazards.
- Safety Checks: Open the control cabinet door and perform electrical circuit tests to confirm that all circuits are inactive and power is effectively turned off. This precautionary measure ensures personal safety before handling any components.
- Remove the Existing EMIO Board:
- Loosen the screws located at the top and bottom of the EMIO board's faceplate, near the ejector tabs. These screws are designed to remain attached to the faceplate.
- Raise the ejector tabs to unseat the module securely.
- Using both hands, carefully pull the board out from the rack, ensuring gentle handling to avoid damage.
- Insert the Replacement Board: Slide the replacement board into the designated slot within the rack, ensuring alignment with the guide rails.
- Seat the Board: Begin seating the board by applying firm pressure simultaneously to the top and bottom of the faceplate using your thumbs. Ensure even pressure distribution for proper alignment.
- Secure the Board: Finish seating the board securely by starting and then tightening the screws at both the top and bottom of the faceplate. Tighten the screws evenly to ensure that the module is seated securely and squarely within the rack slot.
Application Data
- Board Layout: The layout of the EMIO board includes LEDs. The Power LED is linked to the 5 V DC power source, providing a visual indication of power status. The Status LED is connected to the IMOK output from the FPGA, serving as an indicator of the operational status of the board. No jumpers, fuses, or cable connectors are present on the board.
- Cabling Configuration: All cabling from the Input/Output (I/O) boards is connected to the control backplane. Connector P1 facilitates communication with other control boards over the backplane, enabling data exchange and coordination between various components of the control system. Connector P2 serves as the interface to the I/O signals, allowing connectivity with cable connectors situated at the lower part of the EBKP. This arrangement enables the transmission of input and output signals between the board and external devices or sensors.
