GE IS200TPROS1C TPROS1C TERM BD PROTECTIVE – SIL

The GE IS200TPROS1C is a Safety-Rated Protective Terminal Board for the GE Mark VIeS (MKVIeS) turbine control system. Its primary function is to provide a dedicated, high-integrity physical interface for critical protective signals in a Safety Integrity Level (SIL) environment.

Function and Purpose ⚙️

The IS200TPROS1C 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 safety processor. Unlike a standard I/O board, this one is engineered for applications where a failure could lead to a catastrophic event. 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. The “SIL” designation is key, meaning this board is built to meet stringent safety standards.

Related Components 🤝

The IS200TPROS1C works in conjunction with other components of the Mark VIeS system, including:

• Safety Processor Pack (SPRO): The main CPU of the system, which reads the digitized data from the board and executes safety logic.
• 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.
