Allen-Bradley 1771-IR Programmable Logic Controller Module

Allen-Bradley 1771-IR is a six-channel RTD input module for the PLC-5 1771 remote I/O system, designed to interface resistance temperature detectors in industrial control environments. It provides six RTD input channels and is specifically designed to support 3-wire RTD configurations, enabling more accurate temperature measurements across all channels. The module installs in any 1771 I/O chassis and works with PLC-5 processors, making it suitable for temperature monitoring tasks in processes such as furnaces, heat exchangers, and other thermal control applications. With per-channel RTD conditioning and full interoperability within the 1771 I/O family, the 1771-IR integrates into existing PLC-5 installations for straightforward wiring, addressing, and replacement.
