الوصف
The GE IS200SAIIH2A is an Isolated Analog Input Terminal Board for the GE Mark VI (MKVI) turbine control system. Its primary function is to provide a physical connection and a layer of electrical isolation for analog signals from field devices, ensuring the integrity and safety of the control system.
Function and Purpose ⚙️
The IS200SAIIH2A serves as the crucial interface between the turbine’s sensors and the main control processor. It receives continuous, or analog, signals (like those for temperature, pressure, and flow) and routes them to the system’s I/O packs. The “isolated” part of its name is vital, as it means the board is designed to prevent electrical noise, surges, and ground loops from affecting the sensitive electronics of the control system. This is achieved through the use of transformers or opto-couplers, which provide a physical barrier while still allowing data to pass. This feature is critical in harsh industrial environments for ensuring signal accuracy and system protection.
Related Components
The IS200SAIIH2A 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 IS200SAIIH2A.
- I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for signal processing and conversion.
- Field Devices: The board connects to a variety of analog sensors, such as pressure transmitters and thermocouples, to acquire the necessary data.
