Beckhoff BK5120 CANopen Bus Coupler (Economy+), the bridge between a CANopen network and Beckhoff BK51x0 bus terminals, enabling modular expansion of an automated I/O system. As an Economy+ member of the BK51x0 family, the BK5120 connects the CANopen fieldbus to Beckhoff electronic terminal blocks and supports up to 64 bus terminals in a single configuration. It is designed for industrial automation environments where CANopen backbones must be extended with Beckhoff I/O blocks, delivering scalable, centralized control without integrating local I/O on the coupler itself.
