GE IS200TBTCS1B THERMOCOUPLE TERM BO – SIL

الوصف

The GE IS200TBTCS1B is a Safety-Rated Thermocouple Terminal Board for the GE Mark VIeS (MKVIeS) turbine control system. Its main function is to provide a physical connection and cold-junction compensation for thermocouple temperature sensors in a Safety Integrity Level (SIL) environment.

Function and Purpose ⚙️

The IS200TBTCS1B is a crucial component of GE’s safety-rated control solutions. Unlike standard control modules, this board is engineered for applications where a failure could lead to a catastrophic event. It serves as the interface between the turbine’s thermocouples and the main safety processor. The board provides a secure termination point for the wiring from these sensors. It also incorporates cold-junction compensation (CJC) circuitry. CJC is a vital feature that measures the temperature of the terminal board itself to correct for any voltage fluctuations caused by ambient temperature changes. This ensures that the thermocouple’s measured voltage accurately reflects the temperature at the hot junction, providing a highly precise and reliable temperature reading for the safety system.

Related Components 🤝

The IS200TBTCS1B works in conjunction with other components of the Mark VIeS system:

• Safety Processor Pack (SPRO): The main CPU of the system, which reads the digitized temperature data from the I/O packs and executes safety logic.
• Thermocouple I/O Packs: These electronic modules, such as the TCI, mount directly on the terminal board and contain the active electronics for converting the analog voltage into a digital signal that the main processor can use.
• Thermocouple Sensors: These are the actual temperature sensors located in the field, such as on the turbine’s exhaust, bearings, or other critical components
