1794-IF4IXT | Allen-Bradley Flex XT I/O Isolated Analog Input Module

Product Overview

The AB 1794-IF4IXT is a 4-channel isolated analog input module in the Flex XT I/O series. It delivers high-precision signal acquisition for industrial automation and distributed control systems.

This module employs Sigma Delta conversion technology with 16-bit resolution, ensuring accurate measurements from voltage and current sensors. Each input supports ±10 V voltage or 0–20 mA current, accommodating a wide variety of industrial sensors.

Designed for long cable runs, the AB 1794-IF4IXT provides channel-to-channel isolation, reducing signal interference caused by ground potential differences and electromagnetic noise. Its FlexBus interface draws only 50 mA, while the module consumes 2 W of power at 31.2 V DC, with thermal dissipation of 6.8 BTU/hr.

The AB 1794-IF4IXT accepts 2-wire, 3-wire, and 4-wire input sensors, making it versatile for multiple industrial applications. An external 24V DC supply powers the module, providing stable operation in harsh environments.
