Beckhoff BK3150 Profibus DP Compact Bus Coupler

Beckhoff BK3150 PROFIBUS Compact Bus Coupler is a PROFIBUS DP master interface that extends Beckhoff’s BK bus-terminal system in a compact, cost-optimized package. It provides a PROFIBUS DP signaling interface and connects PROFIBUS DP devices to Beckhoff BK terminals via a D-Sub connector, enabling seamless integration of field devices with a Beckhoff controller. As a member of Beckhoff’s BK3xx0 family, the BK3150 delivers a space-efficient solution designed for automation installations where footprint matters while preserving the familiar DP master functionality. Typical applications include distributed I/O networks in manufacturing and process automation where PROFIBUS DP devices must be bridged to Beckhoff control systems, integrating field devices on PROFIBUS with Beckhoff’s modular I/O ecosystem.
