Product Overview
The GE IS200VTURH1BAA is a turbine-specific primary trip board engineered for the Mark VI control system. This industrial automation module plays a pivotal role in safeguarding steam and gas turbines by managing overspeed protection, generator synchronization, and flame detection. Built in the USA, the IS200VTURH1BAA delivers reliable performance in demanding power generation environments.
Key Features & Benefits
-
Turbine Speed Measurement: Uses four passive pulse rate devices to measure turbine speed, feeding data to the controller for primary overspeed trip generation.
-
Overspeed Protection: Controls three primary overspeed trip relays on the TRPG terminal board, triggering emergency solenoids when needed.
-
Generator Synchronization: Automates generator sync and main breaker closure for efficient operation.
-
Flame Detector Monitoring: Oversees eight Geiger Mueller flame detectors in gas turbine applications, with an external power supply of 335 V DC and 0.5 mA.
-
Shaft Monitoring: Tracks induced shaft voltage and current to detect potential issues early.

Industry Applications
This GE IS200VTURH1BAA board is essential in power generation plants, particularly for steam and gas turbines. It is widely used in:
- Gas turbine systems requiring reliable flame detection and overspeed protection.
- Steam turbine installations where precise speed monitoring and synchronization are critical.
- Combined-cycle plants that depend on Mark VI control systems for safe operation.
Its ability to handle multiple safety functions makes the IS200VTURH1BAA a versatile choice for modern turbine control upgrades.
Installation & Setup
Proper installation ensures reliable performance. Follow these steps:
- Power down the VME processor rack completely.
- Align the board with the designated slot and slide it in gently.
- Press the top and bottom levers inward to seat the edge connectors.
- Secure the board using the captive screws on the front panel.
- Power up and test to confirm functionality.
Maintenance & Reliability
Routine inspection of the IS200VTURH1BAA is recommended to ensure long-term reliability. The board's conformal coating protects against moisture and environmental contaminants. Keep the VME rack clean and ensure proper airflow to maintain temperature within the 0 to 60 °C range. Periodic checks of the front panel LEDs (Status, Fail, Run) help verify operational health.
Selection Guide & Purchasing Advice
When selecting this board, verify your system's revision requirements. The IS200VTURH1BAA supports backward compatibility with the first two revisions, making it a drop-in replacement for many existing Mark VI installations. Ensure your VME rack has an available slot and that the power supply meets the board's requirements.
