The Allen-Bradley 1756-IR12 is a ControlLogix analog input module manufactured by Rockwell Automation.
Designed for RTD (Resistance Temperature Detector) applications, it provides 12 channels in a 3-wire RTD configuration for precise temperature measurement.
The module offers a 24-bit resolution and supports input ranges of 1–500, 2–1000, 4–2000, and 8–4000 Ohms.
As part of the Bulletin 1756 product line, the 1756-IR12 is commonly used as a general-purpose analog input device for industrial control systems that require accurate resistance-based temperature monitoring.
It can be installed in any ControlLogix chassis slot and integrates seamlessly with Logix controllers for advanced process control.
