The assembly provides structural backplane interconnects, routing internal communication buses and power rails between central controller nodes and field I\/O termination assemblies. Integrated power plane filtering and isolation elements prevent field-side transient propagation across internal backplane logic channels.\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-SHEDA1\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\u003e3.0 kg (Shipping Weight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e125 mm x 45 mm x 110 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 nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoard Type\u003c\/td\u003e\n\u003ctd\u003eSeries 8 Header Board \/ Backplane Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Platform\u003c\/td\u003e\n\u003ctd\u003eHoneywell Series 8 \/ Experion PKS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003eMulti-pin backplane header connectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eBus-to-ground electrical isolation\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-SHEDA1 incorporates high-density multilayer trace routing designed to maintain signal integrity across analog loops, including those utilizing 4-20 mA HART loop protocol modulations. System-wide channel-to-channel isolation principles are preserved through dedicated bus isolation layers that prevent common-mode voltage spikes and ground loop differentials from propagating across the chassis backplane. High-frequency noise suppression filters are embedded within the header matrix to isolate core processor operations from external field-induced electromagnetic interference.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the main structural function of the 8C-SHEDA1 Header Board?\u003c\/p\u003e\n\u003cp\u003eA: The board serves as the primary physical and electrical header interface, linking internal backplane communication lines and 24 VDC power distribution buses across the Series 8 rack assembly.\u003c\/p\u003e\n\u003cp\u003eQ: How does the 8C-SHEDA1 mitigate cross-talk and system noise across adjacent I\/O channels?\u003c\/p\u003e\n\u003cp\u003eA: Internal ground planes and isolated bus trace topologies isolate individual signal paths, minimizing high-frequency noise injection and cross-channel signal degradation.\u003c\/p\u003e\n\u003cp\u003eQ: Are special procedures required when hot-swapping modules attached to the 8C-SHEDA1 header assembly?\u003c\/p\u003e\n\u003cp\u003eA: Modules attached to the header board must be removed or inserted per Experion Series 8 hot-swap guidelines, ensuring retaining latches are fully disengaged before unseating backplane header pins.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the Series 8 enclosure chassis is bonded to the primary cabinet Earth ground bar using a short, low-impedance copper strap (minimum 4 mm2 \/ 10 AWG).\u003c\/li\u003e\n\u003cli\u003eDe-energize all primary 24 VDC power feeds supplying the backplane rack prior to mounting or unmounting the 8C-SHEDA1 header board assembly.\u003c\/li\u003e\n\u003cli\u003eAlign header board alignment pins carefully with the rack mounting slots to prevent bending multi-pin backplane connectors during mechanical seating.\u003c\/li\u003e\n\u003cli\u003eKeep field signal and power cabling physically separated in dedicated wireways, maintaining a 300 mm clearance from high-voltage AC conductors.\u003c\/li\u003e\n\u003cli\u003eTorque all chassis retention screws to 0.5 to 0.6 Nm to ensure secure mechanical grounding and vibration resistance.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48793873481918,"sku":"8C-SHEDA1","price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/Honeywell8C-TDODA1_6ad8fcbe-076d-4b58-90c0-815106b1d786.png?v=1787887772","url":"https:\/\/www.autooiltech.com\/ar\/products\/honeywell-8c-sheda1-series-8-header-board","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
