Allen-Bradley 1769-IF4I 4-Channel Analog Input Module

Allen-Bradley 1769-IF4I is a four-channel isolated analog input module designed for CompactLogix and Compact I/O systems. It converts and digitally stores analog signals for retrieval by the controller, providing four isolated input channels that are configured as differential inputs. Each channel can accept either current or voltage signals, enabling safe interfacing to a wide range of field sensors while helping to minimize ground-loop and noise issues in industrial environments. The 1769-IF4I mounts on the 1769 Compact I/O backplane and is compatible with CompactLogix controllers as well as MicroLogix 1500 controllers, making it a versatile option for small to mid-sized automation applications. This module’s isolation separates field-side signals from the controller, improving measurement integrity and protecting the control system in demanding industrial settings.
