It provides a shielded 9-pin D-sub PROFIBUS connector and a K-bus interface, with electrical isolation between fieldbus and the power\/supply domain. The unit runs from 24 V DC, drawing 70 mA plus the K-bus current (up to 500 mA total) and supporting up to 1.75 A on the K-bus, with a recommended fuse up to 10 A. Weighing about 170 g, it operates from -25 °C to +60 °C and up to 95% RH (non-condensing); IP20 protection. BK3120 supports PROFIBUS-DP V1 services and carries CE, UKCA, cULus, EAC, GL, ATEX\/IECEx, and cFMus markings, including Ex nA IIC T4 Gc and Ex tc IIIC T135 °C Dc for hazardous locations. Typical use cases include connecting a PROFIBUS DP master to BK-series I\/O in factory automation, process control, and packaging lines requiring a robust fieldbus interface.\u003c\/p\u003e\u003c\/div\u003e","brand":"BECKHOFF","offers":[{"title":"New","offer_id":51676815753518,"sku":null,"price":318.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6ac8fbf3-b149-4b34-9468-2cddbe0ba69d.jpg?v=1769553813","url":"https:\/\/plgautomation.com\/products\/beckhoff-automation-bk3120-nsnbc01-programmable-logic-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
