Allen-Bradley 1734-IR2 2-Channel RTD Input Module

Allen-Bradley 1734-IR2 is a POINT I/O RTD input module that provides two RTD input channels for direct resistance-temperature sensing within a POINT I/O network. It operates on 24 V DC and accepts RTD sensor resistances from 0 to 600 ohms per channel, enabling use with common RTD sensors for temperature measurement. This compact 2-channel module is designed to read two independent RTD measurements and report them to the connected controller through the POINT I/O system. As part of the 1734 POINT I/O family, the 1734-IR2 shares the module form factor, wiring approach, and configuration methodology common to other POINT I/O input modules, facilitating straightforward integration in industrial automation setups. Typical applications include process temperature monitoring, equipment protection, HVAC monitoring, and other on-machine temperature sensing tasks where RTD inputs are required in a two-channel configuration.
