{"product_id":"allen-bradley-1771-ir-input-module","title":"Allen-Bradley 1771-IR Input Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1771-IR Input Module is a six-channel RTD input module for PLC-5 remote I\/O networks, designed to accept and condition RTD temperature sensors and translate their resistance measurements into digital values for the controller. It is specifically designed for 3-wire RTDs and mounts in 1771 remote I\/O racks in compatible chassis such as 1771-A1, A2, and A4 configurations. As part of the 1771 RTD input family, it provides channelized RTD sensing for reliable temperature monitoring across multiple process points, enabling precise data for control decisions without replacing existing I\/O hardware. Typical applications include industrial temperature monitoring in manufacturing lines, chemical processing, and equipment where accurate RTD sensing is critical. The module interfaces with older Allen-Bradley PLC-5\/SLC 500 systems and supports standard wiring practices for RTD sensors, delivering scalable temperature sensing with minimal wiring complexity in legacy automation architectures.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244010066154,"sku":null,"price":386.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-ir-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
