Allen-Bradley 1794-IE8XT | FLEX I/O Analog Input Module

Product Overview

The 1794-IE8XT from Allen-Bradley is an analog input module designed for the FLEX I/O 1794 series, providing precise voltage and current measurements for industrial automation systems. It integrates with an adapter and terminal base to form a complete FLEX system, handling applications typically managed by rack-based I/O modules.

This module includes 12 single-ended, non-isolated inputs. It supports adjustable voltage ranges from 0–10V DC or ±10V DC and adjustable current ranges from 0–20 mA or 4–20 mA. The 1794-IE8XT operates at a nominal 24V DC and requires no calibration, ensuring fast deployment and reliable operation in industrial settings.

The front panel features a 3-position keyswitch, allowing secure installation onto the terminal base. Users should rotate the keyswitch to the correct position once and avoid additional adjustments to prevent damage to the module or terminal base.

The FLEX I/O system, including the 1794-IE8XT, supports up to 8 I/O modules per adapter or power supply, enabling scalable configurations for complex automation setups.
