Product Description
Beckhoff BK3150 PROFIBUS Bus Coupler
The Beckhoff BK3150 is a robust and versatile Bus Coupler that seamlessly connects the Beckhoff Bus Terminal system to the PROFIBUS fieldbus. This compact device acts as a gateway, translating PROFIBUS DP signals into the internal, fieldbus-neutral K-bus format. It automatically detects the connected Bus Terminals and creates a corresponding process image in the PROFIBUS system. The BK3150 supports all Beckhoff Bus Terminals, allowing for highly modular and decentralized I/O configurations. Its automatic baud rate detection from 9.6 kbaud up to 12 Mbaud simplifies network integration, making it an ideal solution for a wide range of industrial automation and control applications.
