The GE IS200STAIS2A is a Simplex Analog Input Terminal Board for the GE Mark VIeS (MKVIeS) turbine control system. Its primary function is to provide a standardized, physical connection point for analog sensors, specifically for use in safety-rated applications.
Function and Purpose ⚙️
The IS200STAIS2A is designed to provide a secure and reliable interface between the turbine’s analog sensors (like thermocouples and pressure transmitters) and the system’s main processor. The “Simplex” designation indicates that this board is used in applications where a single, non-redundant channel for temperature measurement is sufficient. Its use in the Mark VIeS system means it’s built to meet stringent Safety Integrity Level (SIL) standards, making it suitable for safety-critical functions where a failure could lead to dangerous conditions. The board provides a secure termination point for the wiring, which simplifies installation and maintenance, and helps to ensure a clean, stable signal path, which is vital for accurate control and monitoring.
Related Components 🤝
The IS200STAIS2A 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.
- Analog I/O Packs: These electronic modules, such as the IS200AIOS, mount directly on the terminal board and contain the active electronics for signal conditioning and conversion.
- Analog Field Devices: The board connects to a variety of analog sensors to acquire the necessary data for safety monitoring.
