The core function of the analog I/O module is to realize the conversion and transmission between analog signals and digital signals, and the specific process is as follows:
Analog Input (AI) Function
It receives continuous analog signals (such as voltage signals 0-10V, current signals 4-20mA, etc.) from external sensors (such as temperature sensors, pressure transmitters, flow sensors, etc.). Through the internal high-precision A/D (Analog-to-Digital Converter), the analog signals are converted into digital signals. After being processed by the module’s processor, the digital signals are transmitted to the upper-level control system (such as PLC, DCS or turbine controller) through the bus (such as VME bus), so as to realize the real-time collection of industrial process parameters.
