The Allen-Bradley 1756-IF16H is a ControlLogix analog input module with 16 channels and HART communication, designed to live in a 1756 backplane chassis for reading process signals from field devices. It enables a single module to capture data from 4-20 mA sensors and to exchange device information via HART, reducing wiring and enabling on-board diagnostics with HART-equipped transmitters. As part of the 1756 ControlLogix I/O family, it communicates with the PLC over the standard 1756 backplane, supporting integration with Rockwell Automation configuration and diagnostics tools for easy setup and monitoring of sensor networks in process control applications.
