BK3120 Beckhoff Economy Plus Bus Coupler For PROFIBUS DP Networks 12 Mbaud 24 VDC
The Beckhoff BK3120 is a compact and reliable PROFIBUS DP bus coupler designed to connect Beckhoff Bus Terminals (K-bus) directly to a PROFIBUS DP fieldbus network. As a key interface component in distributed automation systems, the BK3120 enables seamless communication between standard digital and analog I/O terminals (such as KL1xxx, KL2xxx, KL3xxx, and KL4xxx series) and any PROFIBUS DP master, including PLCs from Siemens, Rockwell, Schneider, and other major manufacturers.
With support for up to 64 Bus Terminals per station and a data exchange capacity of up to 512 bytes input and 512 bytes output, the BK3120 delivers high-performance I/O connectivity for applications ranging from packaging machines and material handling systems to process skids and test benches. Its integrated PROFIBUS DP slave functionality, LED status indicators, and automatic terminal detection simplify commissioning and reduce engineering time—making it an ideal solution for OEMs and system integrators seeking cost-effective, modular I/O over PROFIBUS.
