The eight-channel configuration supports I\/O density scaling within compact field stations while maintaining channel-level signal processing. The module receives thermocouple and RTD input signals, performs analog conversion at 14-bit resolution, and transfers processed values through the FLEX I\/O communication adapter interface.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1794-IRT8XT be installed as a hot-swappable module during system operation?\u003cbr\u003eA: Hot-swap capability depends on the installed FLEX I\/O adapter, terminal base configuration, and system operating requirements. Module replacement procedures must follow the applicable Allen-Bradley FLEX I\/O installation documentation.\u003c\/p\u003e\n\u003cp\u003eQ: What type of temperature sensors are supported by this input module?\u003cbr\u003eA: The module supports multiple thermocouple types including B, E, J, K, TXK\/XK(L), N, R, S, and T, as well as RTD inputs within the specified millivolt range.\u003c\/p\u003e\n\u003cp\u003eQ: How is field signal isolation handled on the 1794-IRT8XT?\u003cbr\u003eA: The module provides a 50 V continuous isolation rating for the input circuitry. Field wiring should follow recommended shielding and grounding practices for analog temperature measurement circuits.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInstall the module on the FLEX I\/O terminal base assembly using the specified DIN rail mounting arrangement.\u003c\/li\u003e\n\u003cli\u003eVerify that the 24 VDC external supply polarity and voltage level meet the module power requirements before energizing the circuit.\u003c\/li\u003e\n\u003cli\u003eSeparate thermocouple and RTD signal wiring from high-current power conductors and switching loads to reduce electrical interference.\u003c\/li\u003e\n\u003cli\u003eUse appropriate shielded instrumentation cable for low-level temperature signals where required by the installation environment.\u003c\/li\u003e\n\u003cli\u003eTerminate cable shields according to the control system grounding practice to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003eConfirm terminal base connections and channel assignments before commissioning input scaling.\u003c\/li\u003e\n\u003cli\u003eMaintain IP20 enclosure protection by installing the module inside a suitable control cabinet or protected panel.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43778410807386,"sku":"1794-IRT8XT","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1794-IRT8XT2.jpg?v=1785744136","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1794-irt8xt-flex-i-o-thermocouple-rtd-input-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
