Internal signal conditioning provides channel-to-channel isolation and precision cold junction compensation (CJC) for thermocouple inputs, mitigating thermal gradient errors across the field wiring terminals. Digitized temperature data is transferred directly across the Series 8 backplane to the controller for execution in Experion PKS control loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 8C-PAIMA1 51454473-175 support hot-swapping during active system operation?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module supports hot-swapping via the associated Series 8 Input Output Termination Assembly (IOTA) without disrupting power or controller backplane communication to adjacent modules.\u003c\/p\u003e\n\u003cp\u003eQ: How is cold junction compensation (CJC) handled for thermocouple field wiring?\u003c\/p\u003e\n\u003cp\u003eA: Cold junction compensation is executed directly through internal circuitry and temperature sensors integrated into the matching Series 8 IOTA block.\u003c\/p\u003e\n\u003cp\u003eQ: What power rail energizes the low-level signal conditioning circuitry of the module?\u003c\/p\u003e\n\u003cp\u003eA: The module operates from a 24 VDC supply delivered via the Series 8 carrier backplane and IOTA base.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIOTA Mounting\u003c\/strong\u003e: Align the 8C-PAIMA1 51454473-175 module with the dedicated slot on the Series 8 IOTA board and press firmly until the locking tabs snap into place.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Cable Termination\u003c\/strong\u003e: Terminate RTD and thermocouple individual pair cable shields at the designated chassis ground bar to prevent electrical noise from causing measurement drift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Separation\u003c\/strong\u003e: Route low-level RTD and thermocouple field cables in dedicated instrument trays, maintaining isolation from high-voltage AC power and inductive load wiring.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52312929304872,"sku":"8C-PAIMA1 51454473-175","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/8C-PAIMA151454473-175.png?v=1788252671","url":"https:\/\/www.powerdcs.com\/products\/8c-paima1-51454473-175-series-8-low-level-analog-input-rtd-module-honeywell","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
