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

Product Description

The Allen-Bradley 1769-IF4I (Part Number: 1769-IF4I) is a high-precision, 4-channel isolated analog input module designed for the CompactLogix 5370 and MicroLogix 1500 controller platforms. This module is engineered for mission-critical industrial environments where signal integrity is paramount. Unlike standard analog modules, the 1769-IF4I features 750V AC/1060V DC channel-to-channel isolation, preventing ground loops and protecting the system backplane from field-side electrical interference.

Equipped with 16-bit resolution, the 1769-IF4I supports a wide range of voltage and current signals, including 4–20 mA, 0–20 mA, and various bipolar voltage ranges up to ±10V. It allows for both differential and single-ended wiring configurations, making it highly adaptable for complex instrumentation involving flow meters, pressure transmitters, and temperature sensors. Its high-speed conversion rate and high input impedance ensure that rapid process changes are captured with superior accuracy and minimal signal loading.
