The Allen-Bradley 1762-IF4 MicroLogix Analog Input Module is suitable for use in a clean, dry (Pollution degree 2) industrial environment, and in circuits not exceeding Over Voltage Category II (IEC 60664-1). For each module, slot x, words 0 to 3 contain the analog values of the inputs. The module can be configured to use either raw/proportional data or scaled-for-PID data. The module notifies the controller of critical and non-critical errors. The module condition array word 0 contains the error codes that are generated by the module.
