IS200GGXIG5A

Part Number IS200GGXIG5A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS200GGXIG5A is an Expander Load Source Board developed by GE. It is a part of the Mark VI control system. The Expander Load Source Board functions in controlling and isolating the high-voltage power bridge while facilitating connections to various cards within the Innovation Series board rack, such as the BPII and BICI. Its primary function involves converting RS422 signals to fiber-optic signals, allowing for efficient gating of the bridge IGCT switching devices. Notably, the board has the capability to connect with up to twelve power devices, enhancing its versatility and scalability. I/O Connectivity and Communication Interfaces The board features dedicated power supply inputs (J1 through J4) specifically allocated to the GGXI board. These inputs ensure reliable power distribution and supply to support the operation of the board. Power output and feedback connectors (J10 through J12) facilitate the transmission of power and feedback signals to connected devices. 

These connectors are crucial for maintaining efficient power distribution and enabling feedback mechanisms for monitoring and control purposes. Voltage feedback terminals (J15 and J16) are incorporated into the board design to enable the measurement and monitoring of voltage levels within the system. This capability allows for precise voltage regulation and monitoring to ensure optimal performance. Specialized fiber-optic connectors are integrated into the board to enable high-speed data transmission via fiber-optic cables. These connectors facilitate efficient communication between the Expander Load Source Board and other interconnected components, enhancing data transfer speeds and reliability. Connectors such as JFBK establish essential links to the BICI board, while JGATE facilitates connections to the BPII board. These connectors ensure seamless communication and interaction between the Expander Load Source Board and other critical components within the system architecture. Connector J5 serves the crucial function of monitoring control power to the GDPA board, contributing to the overall monitoring and control capabilities of the system. The board integrates grounding stabs (LCOM and DCOM) to segregate quiet and noisy circuits effectively. This segregation minimizes interference and noise, thereby enhancing signal integrity and system reliability. Connectors and Hardware Features The board has four 6-pin connectors (J1, J2, J3, and J4), each with small transformers mounted behind them. These connectors serve as the primary interface for signal transmission and processing, facilitating data exchange between the board and other components. The transformers enhance signal integrity by mitigating noise and distortion. Connectors at J10, J11, and J12 are designed for power output and feedback purposes. They establish robust and secure connections for power transmission and feedback signals, contributing to system stability and efficiency. Components and Diagnostic Elements An isolated serial ID chip provides a unique identifier for the board, facilitating efficient tracking and troubleshooting within the system. The board includes fourteen TP (test point) locations for diagnostic testing and measurement, allowing technicians to monitor critical signals and parameters. Nine LEDs dedicated to diagnostic purposes provide real-time feedback on the operational status and health of various components and subsystems. These LEDs help in identifying potential issues or abnormalities quickly. The board features capacitors and resistors for signal conditioning, filtering, and voltage regulation, ensuring optimal performance and reliability under varying conditions. The board lacks adjustable hardware devices or fuses, relying instead on its design and components for functionality, which simplifies maintenance and reduces failure risk. Integration and Application The board regulates and isolates connections between the Innovation Series board rack and high-voltage power bridge, serving as a termination point for current sensors and bridge attenuators. Its multifaceted connectivity and functionality significantly contribute to efficient control and communication within the system architecture.EXPANDER BOARD
