The GE IS200VTURH1B is a VME Turbine Card for the Mark VI series of GE’s Speedtronic Gas Turbine Control Systems. This specialized board, also known as a VTUR card, is a key component for managing a variety of turbine-specific inputs and outputs, acting as a versatile interface for critical control functions. The ‘B’ suffix indicates an updated or later revision of the board, which may include minor improvements or component changes compared to earlier versions.
Key Features and Functionality
The VTURH1B is a multi-purpose I/O board designed to handle a combination of analog and digital signals specific to turbine operation. Its main functions include:
- Analog and Digital I/O: The card is capable of processing both analog and digital signals. It receives data from various sensors (e.g., pressure, temperature, speed) and sends control commands to different components (e.g., valves, relays).
- Speed Measurement: A key function of the VTUR card is to measure turbine speed. It receives signals from speed sensors (such as magnetic pickups) and processes them to provide accurate speed data to the main controller. This is critical for functions like overspeed protection and fuel control.
- Flame and Combustion Monitoring: The card can interface with flame detectors or other sensors to monitor the status of the combustion process. This data is essential for safe startup and stable operation.
- VMEbus Interface: The card plugs directly into the VME backplane of a Mark VI rack, allowing for high-speed communication with the main controller and other I/O cards in the system.
- TMR Support: The IS200VTURH1B supports Triple Modular Redundancy (TMR) systems. In a TMR setup, three separate VTUR cards are installed, providing a redundant system that enhances the overall reliability and safety of the turbine control system.
