Overview
Analog Input Modules
An analog input (AI) module includes three independent input channels. Each input channel receives variable voltage signals from different points, converts them into digital values, and transmits these values to the three main processor modules on demand. In TMR (Triple Modular Redundancy) mode, one value is selected using a mid-value selection algorithm to ensure accurate data for every scan.
