The 1794-IE8 is an analog input module from Rockwell Automation's Allen-Bradley 1794 Flex I/O series. This module is designed to receive analog input signals and provide them to a programmable logic controller (PLC) system for monitoring and control purposes.

Here are some key features of the 1794-IE8 analog input module:

- It supports up to 8 single-ended or 4 differential analog input channels.

- The module is capable of accepting a variety of analog input signal types, such as voltage, current, and thermocouple inputs.

- It provides high-precision analog-to-digital conversion for accurate measurement and monitoring of analog signals.

- The 1794-IE8 module offers configurable input filter options to reduce noise and improve signal integrity.

- It can be easily configured and integrated into the Flex I/O system using Rockwell Automation's software tools, such as RSLogix 5000 or Studio 5000.

The 1794-IE8 analog input module is commonly used in industrial automation applications where monitoring and control of analog signals are required. It is suitable for a wide range of applications, including process control, temperature monitoring, pressure sensing, and more.
