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

Product Overview

The 1794-IF4IXT is a FLEX XT I/O isolated input analog module from Allen-Bradley/Rockwell Automation. It provides 4 isolated analog inputs for industrial applications. This module handles signals from sensors over long cables. It rejects interference and ground potential differences.

Each channel supports ±10 Volts or 0 to 20 mA. You can configure each input individually for voltage or current. The module works with 2-wire, 3-wire, and 4-wire sensors.

Application Scenarios

Use the 1794-IF4IXT in harsh industrial environments. It suits process control, manufacturing, and oil & gas applications. The extended temperature range (-20 to 70°C) makes it ideal for outdoor or unheated areas. It provides reliable signal isolation for low-voltage field signals.
