Allen Bradley 1769-IF4XOF2 CompactLogix 6-Channel Analog Combination I/O Module

Technical Overview

The 1769-IF4XOF2 (Part Number 1769-IF4XOF2) is a high-performance analog expansion component designed for the CompactLogix and MicroLogix 1500 controller families. This module provides a versatile solution for systems requiring limited analog density, consolidating four high-resolution inputs and two high-speed outputs within a single-slot footprint. By supporting both voltage and current signals, the 1769-IF4XOF2 (1769-IF4XOF2) eliminates the need for separate dedicated modules in smaller applications, significantly reducing hardware costs and cabinet space.

Engineered for precision, the input channels can be configured for either differential or single-ended operation, providing flexibility in sensor wiring and noise rejection. The output channels are designed for rapid response, making them suitable for controlling proportional valves, variable frequency drives (VFDs), and other actuators requiring real-time modulation.

Technical FAQ

Can I mix voltage and current signals on the same module?Yes, each channel on the 1769-IF4XOF2 (1769-IF4XOF2) is individually configurable via software, allowing you to run a 0-10V sensor on one input and a 4-20mA sensor on another simultaneously.

Does this module require an external power supply?While the logic is powered by the CompactLogix backplane, the analog circuitry requires 24V DC power, which is typically supplied through the backplane by a 1769-series power supply.

Is it possible to use this with a MicroLogix 1500 controller?Yes, the 1769-IF4XOF2 (Part Number 1769-IF4XOF2) is fully compatible with the MicroLogix 1500 LRP and LSP processors when used with the appropriate expansion cable or base.
