Product Overview
The 1756-IR12 is an Allen-Bradley ControlLogix module providing twelve RTD (Resistance Temperature Detector) input channels. It integrates into a ControlLogix I/O chassis via the system backplane. The device converts RTD resistance into IEEE 32-bit floating-point temperature values using a sigma-delta converter. It is used in process monitoring, temperature logging, and industrial control systems requiring multiple temperature inputs in a single module.
