GE IS200TEFVH1A T BOARD ELEC FUEL VA

The GE IS200TEFVH1A is a Terminal Board for an Electronic Fuel Valve for the GE Mark VI (MKVI) turbine control system. Its main function is to provide a physical interface and signal conditioning for the electronic fuel valve’s control signals and feedback.

Function and Purpose ⚙️

The IS200TEFVH1A serves as the crucial link between the MKVI’s main processor and the turbine’s electronic fuel valve. This valve controls the precise flow of fuel to the combustor, which directly impacts the turbine’s speed and power output. The board handles:

• Control Signals: It receives digital commands from the controller and converts them into the precise analog signals (e.g., current or voltage) required to operate the servo valve.
• Feedback Signals: It processes feedback from the valve’s position sensors (e.g., LVDTs), converting the analog position signal into a digital format that the controller can use for closed-loop control.

This board ensures that the sensitive control electronics are properly connected to the high-power valve circuitry and that the signals are conditioned to be accurate and reliable.

Related Components 🤝

The IS200TEFVH1A works in conjunction with other components of the Mark VI system, including:

• Processor Cards: The main CPU of the system sends the digital commands and receives the position feedback data.
• I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for digital-to-analog and analog-to-digital conversion.
• Electronic Fuel Valve: The board connects to the electronic fuel valve to facilitate the control and feedback loops.
