It supports up to 64 DP bus terminals (255 with K-bus extension) and operates from a 24 V DC supply using a D-sub 9-pin bus connection; the module measures 50 mm wide, 100 mm high, 68 mm deep, weighs about 170 g, and mounts on a 35 mm DIN rail with IP20 protection. Electrical specifications include a 24 V DC supply with about 70 mA base current plus K-bus current (max 500 mA total), 2.5× starting current, and 500 V dielectric strength between power and fieldbus; a recommended fuse of up to 10 A is advised. Operating conditions span -25°C to +60°C (ambient) with up to 95% relative humidity (non-condensing); it complies with EN 60068 vibration\/shock requirements and EN 61000 EMC immunity\/emission standards. Certifications on the type plate include CE, UKCA, cULus, EAC, GL, IECEx and ATEX markings, reflecting Beckhoff's global deployment for PROFIBUS applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Beckhoff","offers":[{"title":"New Surplus No Box","offer_id":51676815851822,"sku":null,"price":261.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bbaf9721-8868-4cf4-9b18-1916922de5a6.jpg?v=1769553814","url":"https:\/\/plgautomation.com\/products\/beckhoff-automation-bk3120-industrial-computer","provider":"PLG Automation ","version":"1.0","type":"link"}
