Acting as a DeviceNet® Bus Coupler, it links the DeviceNet® network with Beckhoff’s modular Bus Terminals, allowing direct communication between sensors, actuators, and controllers. The coupler automatically detects data transfer rates and supports up to 64 terminals, or 255 when using the K-bus extension technology. It enables flexible configuration and advanced communication modes such as bit strobe, polling, cyclic, and change of state. Fully compliant with DeviceNet® specifications, the BK5220 provides electrical isolation, robust 24 VDC operation, and CE-certified reliability for harsh industrial conditions. Key Features: Modular Network Expansion: Connects up to 64 terminals, expandable to 255 using K-bus extension technology. High Signal Capacity: Supports up to 1,020 digital and 256 analog I/O signals per DeviceNet® slave. Automatic Communication Setup: Detects baud rates automatically for simplified installation and commissioning. Versatile Operating Modes: Includes bit strobe, polling, cyclic, and change of state (COS) modes for flexible data exchange. Robust Electrical Design: Offers 500 V isolation between supply voltage and power contacts for increased safety. Reliable Power Management: Provides 24 VDC supply with up to 10 A on power contacts and 1.75 A K-bus current. Space-Efficient Construction: Compact 51 mm width saves control cabinet space while maintaining high functionality. Wide Environmental Tolerance: Operates from -25°C to +60°C with IP20 protection and 95% humidity tolerance. The BK5220 delivers the reliability and precision required for DeviceNet® communication, distributed I/O integration, and scalable automation system connectivity.
