This unit serves as a high-availability bridge, allowing the CEX-Bus to be partitioned into two distinct segments separated by distances of up to 200 meters. By enabling the use of redundant communication interfaces and supporting the extension of RCU-Link signals, the BC820 ensures that critical automation networks remain robust and fault-tolerant. The module is engineered to support professional-grade uptime requirements, featuring native support for hot-swapping and online CPU replacement without interrupting system processes.\u003c\/p\u003e\n\u003ch3\u003eCore Hardware Parameters and Environmental Data\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eTechnical Specification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetail Value\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eModel Designation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBC820K02 (Interconnection Kit)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOrder Number\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3BSE071500R1\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eNominal Supply Voltage\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24 V DC (Range: 19.2 to 30 V DC)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e120 mA typical \/ 200 mA maximum\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eHeat Dissipation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.9 W\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eRedundancy Support\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eYes (RCU-Link and Power)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eDimensions (Unit)\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e185 mm (H) x 59 mm (W) x 127.5 mm (D)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eTotal Kit Weight\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e1.4 kg (3.1 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eProtection Standard\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP20 (EN 60529)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOperating Limits\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e+5 to +55 °C\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eProcessor Compatibility:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFully compatible with PM858, PM862, PM866, and PM866A controller units.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInterface Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eManages up to 6 CEX-Bus interfaces per interconnection unit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eExpansion Limits:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eExtends physical bus and RCU-Link cable reach to a maximum of 200 meters via optical and copper links.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHot Swap Capability:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDesigned for maintenance and module replacement while the system remains energized.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eKit Contents:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIncludes 2x BC820 units, 2x TP850 baseplates, 2x TK857 RCU-link cables, and 2x TB850 terminators.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIndustrial Deployment Contexts\u003c\/h3\u003e\n\u003cp\u003eThis interconnection unit is primarily utilized in large-scale Distributed Control Systems (DCS) where geographical separation of hardware or high levels of fault tolerance are mandatory. In sectors such as oil and gas or power generation, the BC820K02 allows engineers to place redundant communication modules in different physical cabinets to prevent a localized failure from compromising the entire network. Its Swiss-engineered reliability makes it a staple for maritime applications, as evidenced by its ABS and DNV-GL certifications. Furthermore, the 200-meter extension capability is vital for sprawling manufacturing facilities that require synchronized control over extended distances without degrading signal integrity or increasing latency.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the BC820K02 kit include the 200-meter long-distance fiber optic cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No, the long-distance RCU Control Link (RJ45 crossover) and RCU Data Link (OM3 fiber) cables are not included in the kit and must be sourced separately to meet the specific length requirements of your installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the BC820 operate without an external power supply?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: While the BC820 can draw power directly from the processor via the CEX-Bus, utilizing the external power connector is highly recommended to provide redundant power and ensure the highest level of system availability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which fiber optic connector type is required for the RCU Data Link?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The unit is compatible with LC Duplex optical connectors conforming to ANSI TIA\/EIA60-10 standards, specifically optimized for 50\/125μm OM3 multimode fiber.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this module suitable for use in explosive atmospheres?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes, the BC820K02 carries cULus Class 1, Zone 2, and ExnA IIC T4 Gc X certifications, making it suitable for hazardous locations where specific safety protocols are required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum number of CEX-Bus interfaces supported by a single unit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Each BC820 interconnection unit is limited to supporting a maximum of 6 CEX-Bus interfaces to maintain optimal signal performance and processing speed.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":45866949640365,"sku":"3BSE071500R1","price":1999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/1_829d08bc-996b-43f0-a916-4fdb48102e3b.jpg?v=1774600036","url":"https:\/\/www.maxwellplc.com\/products\/3bse071500r1-abb-cex-bus-interconnection-unit-bc820k02-kit-ac-800m","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
