BK3150 PROFIBUS Economy plus Bus Coupler

The Beckhoff BK3150 is a PROFIBUS DP Compact Bus Coupler that connects Beckhoff's modular Bus Terminal system to a PROFIBUS network. It is a cost-optimized variant in a compact housing, supporting up to 64 Bus Terminals directly (expandable to 255 with K-bus extension). The coupler features automatic baud rate detection up to 12 Mbaud and two address selection switches, making it a straightforward gateway for integrating Beckhoff I/O into PROFIBUS DP architectures.
