Allen-Bradley 1769-IF4I Programmable Logic Controller Module

Allen-Bradley 1769-IF4I is a four-channel isolated analog input module for the 1769 Compact I/O family, designed to plug into a 1769 backplane and feed data to a CompactLogix controller. Each of its four inputs can be configured to accept either current (4–20 mA) or voltage (0–10 V) signals, with galvanic isolation between channels to guard against ground loops and transients. The module is commonly used to monitor analog process variables such as temperature, pressure, level, and flow by connecting field sensors and transmitters, enabling reliable, scalable data acquisition within Rockwell Automation's ecosystem. It integrates with Rockwell Automation software and 1769-series I/O timing and configuration for straightforward deployment in industrial applications.
