Functional Capabilities

The module serves as an intermediary between field instrumentation and the turbine control processor:

1. Signal Acquisition – Receives electrical signals from sensors
2. Signal Processing – Performs filtering, scaling, and conversion
3. Data Transmission – Sends processed data to the main controller
4. Control Feedback – Outputs control signals to actuators (valves, motors)

This closed-loop operation ensures stable turbine speed, temperature, and pressure control under varying load conditions.
