The 1794-IRT8XT module is an analog input module made by Allen-Bradley, which is a brand under Rockwell Automation. This module is part of the Allen-Bradley Flex I/O system, which is a modular I/O platform used in industrial automation applications.

The 1794-IRT8XT module is designed to convert analog input signals from field devices, such as temperature sensors or pressure transmitters, into digital signals that can be processed by a programmable logic controller (PLC) or other control devices. It has eight individually isolated analog input channels, which provide high-resolution and high-accuracy analog-to-digital conversion.

The module supports a wide range of input signal types, including voltage, current, resistance, and thermocouple inputs. It also offers features like channel-to-channel isolation and on-channel cold junction compensation for thermocouple inputs.

The 1794-IRT8XT module can be used with various Allen-Bradley PLC platforms, such as the ControlLogix and CompactLogix controllers, by connecting it to the I/O chassis via a communication backplane.
