Product Description:

The BK5100-0000 EtherCAT bus coupler from Beckhoff is an outstanding communication solution for industrial automation applications. At its core is a robust yet flexible design that facilitates high-speed data transmission throughout the system. Using standard RJ45 connectors, it integrates seamlessly into EtherCAT networks and supports transfer rates up to 100 megabits per second. This empowers fast updates between controllers and peripheral devices down to the field level for tightly coordinated processes.

Versatile connectivity is another major advantage. The coupler accommodates up to 64 terminals directly and a maximum of 255 when using K-bus extensions. This allows for highly scalable configurations to match evolving requirements. It also accepts mixed terminal types on a single coupler, whether handling digital, analog, or servo motion I/O. Extensive terminal options thus make the BK5100-0000 a valuable asset for diverse automation tasks.

Reliable operation over long lifecycles is ensured by selections like reinforced high-temperature capacitors. Its operating ambient is an industrial-suitability -25 to 60 degrees Celsius. Further assuring uptime is protection against transients and short circuits on the K-bus through current limiting. Rigorous ongoing testing by Beckhoff also guarantees compliant, lasting field performance within specification. With powerful integrated features and a modular terminal concept, this EtherCAT coupler streamlines machine building. Compact dimensions and DIN-rail mounting let it neatly integrate into control cabinets. And 550mA of available current supply via the K-bus permits distributed peripheral intelligence as needed. Overall access, wiring, and expandability are optimized for productivity.
