Powered by an external 24 VDC source, this DIN-rail mounted open-style adapter provides a dual-media redundant communication bridge between up to eight FLEX I\/O functional modules and a primary ControlNet network controller.\u003c\/p\u003e\n\u003ch3\u003eMedia Redundancy and Extended Temperature Protection\u003c\/h3\u003e\n\u003cp\u003eDesigned for harsh industrial environments, the module features dual BNC connectors (Channel A and Channel B) to maintain active redundant ControlNet links. The \"XT\" designator and internal conformal coating protect circuit components from corrosive atmospheres, moisture, and extreme ambient operating temperatures ranging from -20 deg C to +70 deg C (-4 deg F to +158 deg F).\u003c\/p\u003e\n\u003ch3\u003ePower Distribution and Network Configuration\u003c\/h3\u003e\n\u003cp\u003eThe adapter converts external 24 VDC input power to supply 5 VDC logic power across the Flexbus backplane, supporting up to 640 mA output current for connected terminal base units. Rotary thumbwheel switches located on the front panel allow quick hardware setting of the ControlNet node address (01 to 99) without needing dedicated configuration software.\u003c\/p\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\u003e1794-ACNR15XT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley (Rockwell Automation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eControlNet Redundant Media Adapters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Protocol\u003c\/td\u003e\n\u003ctd\u003eControlNet (Dual BNC Coaxial Ports)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (19.2 to 31.2 VDC range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Power Consumption\u003c\/td\u003e\n\u003ctd\u003e400 mA @ 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlexBus Output Current\u003c\/td\u003e\n\u003ctd\u003e640 mA max @ 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to +70 deg C (-4 to +158 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Coating\u003c\/td\u003e\n\u003ctd\u003eConformal Coated (ISA\/ANSI-71.040 Class G3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Rating\u003c\/td\u003e\n\u003ctd\u003eIP20, Open Style\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN Rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e87.4 x 94 x 92 mm (3.4 x 3.7 x 3.6 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.31 lbs (approx. 220 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary difference between the standard 1794-ACNR15 and the 1794-ACNR15XT? A: The 1794-ACNR15XT features conformal coating and extended-temperature components that allow reliable operation in harsh environments from -20 deg C to +70 deg C, compared to the standard 0 deg C to +55 deg C operating range.\u003c\/p\u003e\n\u003cp\u003eQ: How is the ControlNet node address configured on this adapter? A: The network address (01 to 99) is set directly using two rotary thumbwheel switches located on the front face of the module.\u003c\/p\u003e\n\u003cp\u003eQ: How does the dual media interface maintain continuous communication? A: The adapter features two separate BNC coax ports (Channels A and B) that connect to dual ControlNet cabling runs, providing instant hardware-level media redundancy if one cable is damaged or disconnected.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":66999916789875,"sku":"1794-ACNR15XT","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1794-ACNR15XT_Cocoai_765ce6ac-5602-491c-9c10-031155138cc7.jpg?v=1793007820","url":"https:\/\/www.dcssupplier.com\/ar\/products\/allen-bradley-1794-acnr15xt-flex-i-o-controlnet-redundant-adapter-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
