BK2020 - Beckhoff EtherCAT Bus Couplers

The Beckhoff BK2020 Bus Coupler is designed for high-performance connectivity with fiber-optic transmission, ensuring stable communication in distributed automation systems. It supports up to 64 Bus Terminals and can be expanded to 255 with K-bus extension. The device handles 512 input and 512 output bytes, operating at 2.5 Mbaud with automatic detection. Using APF plastic fibers (distance up to 45 m) or HCS fibers (distance up to 300 m), it ensures flexibility in system design. The 24 V DC power supply with a maximum input current of 500 mA supports stable operation, while 500 V electrical isolation provides safety in industrial environments.

With a 1750 mA K-bus current supply, the BK2020 can manage 1,020 digital signals and 128 analog signals efficiently. Its compact polycarbonate housing measures 51 x 100 x 69 mm, integrates signal LEDs for diagnostics, and installs on standard 35 mm DIN rails. Lightweight at 150 g, the coupler withstands temperatures from 0°C to +55°C, vibration per EN 60068, and complies with EN 61000 EMC standards. Certified with CE, UL, ATEX, and IECEx markings, it is globally accepted for safe and reliable use in industrial systems.

The BK2020 Bus Coupler is widely applied in factory automation, robotics, material handling, and process control systems requiring long-distance, high-speed data communication. Junior engineers value its straightforward configuration via KS2000 or controller setup, while senior professionals rely on its fast response time of 0.26 ms for demanding applications. Maintenance engineers benefit from its LED diagnostics and durable build, reducing downtime in the field. For engineers seeking a reliable EtherCAT Bus Coupler that supports scalability and fiber-optic integration, the Beckhoff BK2020 is a proven solution.
