The DCS analog input (AI module) and analog output (AO module) serve as the core interface connecting field sensors and actuators with the main controller. These modules are responsible for high-precision acquisition, conversion, and output of analog signals, ensuring continuous control over critical parameters such as pressure, temperature, and flow regulation.
