GE IS200WROGH1A WROG DIST POWER AND SENSING BOARD

الوصف

The GE IS200WROGH1A is a WROG Distribution Power and Sensing Board for GE’s Mark VI, Mark VIe, and Mark VIeS turbine control systems. This board is a specialized component used in conjunction with a main I/O board (like a TRLY) to provide fused and monitored power to field devices.

Key Features and Functionality

The WROGH1A is a crucial component for ensuring the safe and reliable operation of relay-controlled devices. Its primary functions include:

• Power Distribution: The board provides a dedicated power source and fusing for the relays that drive field devices. It is designed to work with various power sources, including 125 VDC, 115 VAC, or 24 VDC, depending on the system’s configuration.
• Fused Circuits: A primary feature of the board is its fused circuits. It typically has multiple fused branches to protect individual relay circuits from overcurrents or short circuits. This prevents a single fault in the field from affecting the entire I/O card or the control system.
• Power Sensing and Diagnostics: A key feature of the WROG board is its ability to sense the power status of the relays. It continuously monitors the voltage across the fuses and the relay circuits. If a fuse blows or power is lost, the board detects this and sends a diagnostic signal to the main Mark VI controller. This provides valuable diagnostic feedback to the operator, allowing for quick troubleshooting and maintenance.
• Daughter Board Design: The IS200WROGH1A is designed as a small daughter board that plugs directly into a compatible main VME I/O card. This modular design simplifies installation and replacement.
