Allen Bradley 1794-IR8 Flex I/O RTD Input Module

Product Introduction

The Allen-Bradley 1794-IR8 FLEX I/O RTD Input Module is a precision analog input module specifically designed for temperature measurement using RTD (Resistance Temperature Detector) sensors. As part of the FLEX I/O platform from Rockwell Automation, this module delivers accurate and stable temperature data acquisition in distributed industrial control systems.

With 8 input channels and support for RTD signals within a nominal range of 1–433 ohms, the 1794-IR8 enables precise monitoring of temperature variations in critical processes. Its 16-bit resolution ensures high accuracy, making it suitable for applications where fine measurement detail is essential.

The module is designed for DIN rail mounting and integrates seamlessly into FLEX I/O systems, providing reliable performance and efficient installation in industrial environments.
