{"product_id":"allen-bradley-1756-irt8i-digital-input-module","title":"Allen-Bradley 1756-IRT8I Digital Input Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1756-IRT8I is an eight‑channel analog input module for Rockwell Automation ControlLogix 1756 backplanes, designed to read RTD and thermocouple sensors with channel‑to‑channel isolation. Each channel can be configured for RTD sensing (Pt100\/Pt1000 variants) or thermocouple input, with per‑channel support for a wide range of thermocouple types including J, K, N, R, S, T, E, B, and TXK\/XK (L); specific temperature ranges vary by type—for example Type J covers roughly -210 to +1200 °C, Type K -270 to +1372 °C, Type N -270 to +1300 °C, Type R\/S -50 to +1768 °C, Type T -270 to +400 °C, and TXK\/XK (L) -200 to +800 °C. The module’s inputs are isolated, aiding noise rejection and safeguarding the controller and field wiring in industrial environments. Wiring is via a removable TBCH terminal block, with single‑wire connections in the 0.33–2.1 mm² (22–14 AWG) range using shielded copper conductors rated up to 105 °C. As a ControlLogix I\/O module, it occupies a single backplane slot and communicates over the 1756 I\/O bus to the PLC, providing per‑channel measurements suitable for precise temperature monitoring in applications such as process control, HVAC, and manufacturing equipment. Available variants include 1756-IRT8I\/A and 1756-IRT8IK\/A, which reflect different packaging or configuration options while preserving eight input channels and the RTD\/thermocouple capability. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659667800366,"sku":null,"price":505.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d24513a2-fde7-4b89-a475-71d4124dbca5.jpg?v=1769529696","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-irt8i-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
