Allen-Bradley 1756-IF8 Analog Input Module for ControlLogix

Allen-Bradley 1756-IF8 is an eight-channel analog input module for Rockwell Automation's ControlLogix platform, designed to plug into a 1756 backplane and collect real-time sensor data from field devices. It accepts both current and voltage signals on eight channels through a 36-pin I/O interface, supporting voltage inputs in a ±10 V range and current inputs in the 4-20 mA range. This module is intended for use with ControlLogix controllers to read transmitter outputs and process signals for monitoring and control in industrial environments. The 1756-IF8 is the non-isolated variant in the 1756-IF8 family (an isolated version is available as 1756-IF8I if your application requires isolation between field signals and backplane). It integrates with Rockwell's design tools and can be configured in RSLogix 5000/Studio 5000, enabling straightforward mapping of each channel to tags and scalable I/O. Its eight-channel, dual-range input design provides flexibility for mixed signal environments, allowing engineers to optimize wiring and hardware in a single module.
