High galvanic isolation isolates the hazardous field circuit from non-hazardous control system I\/O and auxiliary power networks. Internal safety barriers enforce strict voltage, current, and power limits under worst-case fault conditions, preventing thermal or spark ignition in flammable dust or gas atmospheres.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDIN-Rail Mounting and Thermal Clearance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSnap the module vertically onto a 35 mm DIN mounting rail (EN 60079-15) or position directly onto an integrated Power Rail system busbar.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum vertical clearance of 50 mm above and below the housing to facilitate natural thermal dissipation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWiring Isolation and Shield Grounding\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaintain a minimum separation distance of 50 mm between intrinsically safe blue terminals and non-intrinsically safe power or signal lines.\u003c\/li\u003e\n\u003cli\u003eRoute field cables using twisted-pair shielded cabling and terminate the shield to a single ground point on the main enclosure ground bar.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePrimary Product Code: KFD2-STC5-Ex1.H\u003c\/li\u003e\n\u003cli\u003eBox Contents: 1x KFD2-STC5-Ex1.H SMART transmitter power supply module, 1x set of removable screw terminals, 1x quick start manual.\u003c\/li\u003e\n\u003cli\u003eCompatible Rail Accessories: Power Rail UPR-03, Power Feed Module KFD2-EB2.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the KFD2-STC5-Ex1.H support bi-directional HART communication signals? A: Yes, the module supports HART communication protocols by passing bi-directional high-frequency digital signals over the 4-20 mA analog loop.\u003c\/p\u003e\n\u003cp\u003eQ: Can this module power both 2-wire and 3-wire transmitters? A: Yes, terminal connections allow wiring configurations for both 2-wire powered transmitters and 3-wire current source instruments.\u003c\/p\u003e\n\u003cp\u003eQ: How is the module powered during standard cabinet operation? A: Auxiliary 24 VDC power can be applied directly to terminals 14+ and 15- or supplied through the DIN-rail mounted Power Rail system.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum peak isolation voltage for the internal barrier? A: Safe galvanic isolation provides voltage peak isolation up to 375 V between hazardous field inputs, control side outputs, and supply terminals in compliance with EN 60079-11.\u003c\/p\u003e","brand":"Pepperl+Fuchs","offers":[{"title":"Default Title","offer_id":47508764557485,"sku":"KFD2-STC5-EX1.H","price":193.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/KFD2-STC5-1_1.jpg?v=1777268975","url":"https:\/\/www.maxwellplc.com\/ga\/products\/kfd2-stc5-ex1-h-pepperl-fuchs-smart-transmitter-power-supply-k-system","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
