The Beckhoff BK5220 DeviceNet® Bus Coupler provides a powerful interface between Beckhoff’s modular Bus Terminal system and DeviceNet® fieldbus networks. Designed for flexibility and scalability, the BK5220 offers engineers and system integrators a cost-effective and robust solution for integrating distributed I/O into industrial automation systems.

One of the key advantages of the BK5220 is its ability to connect up to 64 Bus Terminals directly, supporting a wide range of digital and analogue modules. With the addition of a K-bus extension, this capacity can be expanded to 255 Bus Terminals, making the coupler suitable for large-scale applications requiring extensive I/O capacity. This scalability ensures it can adapt to both small machine-level control systems and complex plant-wide architectures.

The coupler supports a high I/O density, with up to 1,020 digital inputs/outputs and 256 analogue inputs/outputs. This versatility allows engineers to configure systems that meet precise application requirements, whether handling high-speed digital switching or managing precise analogue measurements. The combination of digital and analogue support provides flexibility across industries such as packaging, process automation, material handling, and building automation.

Data handling capabilities are another strength of the BK5220. It can process up to 512 bytes of input and 512 bytes of output fieldbus data, ensuring efficient communication between the field devices and the DeviceNet® master. This capacity is well-suited for complex systems where large amounts of real-time data must be exchanged reliably.

The configuration process is straightforward and can be carried out using KS2000 configuration software or directly via the controller. This gives engineers the flexibility to choose the method that best suits their workflow, whether during commissioning, troubleshooting, or system expansion.

Integration into DeviceNet® networks is simplified with the coupler’s automatic baud rate detection, which eliminates the need for manual configuration of data transfer rates. By automatically adjusting to the network, the BK5220 reduces setup time and minimises the potential for configuration errors.

For connectivity, the coupler features a 5-pin open pluggable connector (included), ensuring secure and standardised integration into DeviceNet® fieldbus systems. This robust interface guarantees stable operation even under the conditions typical of industrial environments.

In summary, the Beckhoff BK5220 DeviceNet® Bus Coupler combines scalability, flexibility, and ease of use in a compact and rugged package. With its ability to support up to 255 Bus Terminals, handle large volumes of input/output data, and automatically adapt to network transfer rates, it provides a dependable solution for integrating distributed I/O into DeviceNet® automation systems. Built to Beckhoff’s standards of quality and reliability, the BK5220 ensures long-term, stable operation in demanding industrial applications.
