1.Product positioning and core functions
Module Type
-Analog input module(AI):Responsible for collecting analog signals from sensors such as temperature,pressure,flow,etc.(such as 4–20mA,0–5V)and converting them into digital signals that the system can process.
Core functions
-High-precision signal processing:supports multiple isolated inputs,with signal conditioning and fault diagnosis functions;
-Redundant design:adopts triple modular redundancy(TMR)architecture to ensure that single point of failure does not affect system operation;
-Hot-swap support:allows live replacement of modules to reduce downtime.
