The GE IS200TPROH1B is a Protective Terminal Board for the GE Mark VI (MKVI) turbine control system. Its main function is to provide a dedicated, high-integrity physical interface for critical protective signals.
Function and Purpose ⚙️
The IS200TPROH1B is a crucial component in the turbine’s protection and safety system. It acts as the bridge between sensors that monitor critical parameters (e.g., overspeed, high vibration, flame detection) and the main control processor. Unlike a standard I/O board, this one is designed with enhanced features to ensure signal integrity and prevent spurious trips. It provides a secure and organized termination point for the wiring, which simplifies installation and maintenance, and it typically incorporates features like optical isolation to protect the sensitive electronics from electrical noise and transients.
Related Components 🤝
The IS200TPROH1B works in conjunction with other components of the Mark VI system, including:
- Processor Cards: The main CPU of the system, which reads the digitized data from the board.
- I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for signal processing and conversion.
- Protective Sensors: The board connects to a variety of sensors that are part of the turbine’s safety and protection circuits.
