The assembly establishes deterministic physical links across dual-redundant Fault Tolerant Ethernet (FTE) networks and Profibus DP fieldbus nodes via dedicated onboard connectors. Conformal coating across the printed wiring assembly provides environmental resistance against corrosive contaminants, moisture, and industrial particulates.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e8C-TPOXA1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.45 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e155 mm x 120 mm x 45 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24 VDC (430 mA module current rating)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssembly Type\u003c\/td\u003e\n\u003ctd\u003eIOTA PWA (Input\/Output Terminal Assembly)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoating\u003c\/td\u003e\n\u003ctd\u003eConformal coated PCB protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Connectors\u003c\/td\u003e\n\u003ctd\u003eFTE A (Yellow CAT5e), FTE B (Green CAT5e), DB9F (DP network)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Support\u003c\/td\u003e\n\u003ctd\u003eConfigurable dual-IOTA hardware redundancy via sync cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification Compliance\u003c\/td\u003e\n\u003ctd\u003eUL, CE, RoHS compliant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol \u0026amp; Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe 8C-TPOXA1 incorporates high-speed backplane routing logic designed to bridge field I\/O communications, including HART loop protocol data streams, directly to the primary controller architecture. Dual FTE A and FTE B network interfaces ensure uninterrupted command propagation through independent Ethernet paths, while a dedicated CAT5e redundancy sync port enables sub-millisecond hardware tracking between paired IOTAs. Integrated isolation design principles isolate internal logic circuits from fieldbus common-mode potential shifts and electrical noise spikes across connected DP networks.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is hardware redundancy executed between dual 8C-TPOXA1 assemblies?\u003c\/p\u003e\n\u003cp\u003eA: Redundancy is established by interconnecting two 8C-TPOXA1 IOTAs using a dedicated CAT5e redundancy sync cable, enabling synchronized state tracking and seamless switchover.\u003c\/p\u003e\n\u003cp\u003eQ: What are the distinct roles of the yellow and green RJ45 connectors on the assembly?\u003c\/p\u003e\n\u003cp\u003eA: The yellow connector handles primary Fault Tolerant Ethernet link A (FTE A), while the green connector handles secondary redundant link B (FTE B).\u003c\/p\u003e\n\u003cp\u003eQ: What protection does the conformal coating provide in harsh operating environments?\u003c\/p\u003e\n\u003cp\u003eA: The factory coating forms a protective barrier over surface-mount components, preventing short circuits caused by moisture condensation, chemical vapor exposure, and airborne conductive dust.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eBond the IOTA carrier chassis directly to the enclosure main Earth ground bar using a low-impedance copper conductor (minimum 4 mm2 \/ 10 AWG).\u003c\/li\u003e\n\u003cli\u003eDe-energize the 24 VDC system power feeds prior to attaching or disconnecting fieldbus cables and IOTA interconnect assemblies.\u003c\/li\u003e\n\u003cli\u003eRoute FTE A (yellow) and FTE B (green) CAT5e industrial cables through separate wireways to ensure physical redundancy path separation.\u003c\/li\u003e\n\u003cli\u003eEnsure the DB9F connector for the DP network is fully seated and secured with its retaining screws to maintain continuous shield continuity.\u003c\/li\u003e\n\u003cli\u003eVerify that the dedicated redundancy sync cable is firmly locked into the designated sync port before powering up paired redundant IOTA configurations.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48793864536254,"sku":"8C-TPOXA1","price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/Honeywell8C-TDODA1.png?v=1787887714","url":"https:\/\/www.autooiltech.com\/products\/honeywell-8c-tpoxa1-communication-modules","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
