Allen-Bradley 1797-IRT8 RTD/Thermocouple Input Module – FLEX I/O Series
When a temperature sensor fails to communicate with your control system, the consequences cascade fast — process shutdowns, unplanned downtime, and in critical industries like oil & gas or pharmaceuticals, potential safety incidents. The Allen-Bradley 1797-IRT8 RTD Input Module is the precision interface that keeps your thermal measurement loop intact, converting raw resistance or millivolt signals from RTD and thermocouple sensors into accurate, actionable data for your Rockwell Automation control system. Without it, your FLEX I/O rack loses its eyes on temperature — and your process loses its safety net.
Within the FLEX I/O 1797 series, the 1797-IRT8 occupies a specialized niche: it is the 8-channel universal input module designed to handle both RTD (Resistance Temperature Detector) and thermocouple sensor types in a single compact form factor. This dual-input capability makes it one of the most versatile temperature acquisition modules in the Rockwell Automation portfolio, widely deployed across global process industries where multi-sensor temperature monitoring is a baseline requirement for compliance and quality control.
