The GE IS200STAIS3A is a Safety-Rated Analog Terminal Board for the GE Mark VIe (MKVIe) turbine control system. Its main function is to provide a dedicated, non-redundant interface for analog signals from field devices, specifically designed for use in safety-critical applications.
Function and Purpose ⚙️
The IS200STAIS3A is designed to provide a secure and reliable interface between the turbine’s analog sensors (such as thermocouples and pressure transmitters) and the system’s main processor. The “Safety-Rated” designation indicates that this board is 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 IS200STAIS3A works in conjunction with other components of the Mark VIe 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.
