Information About BK3150
The BK3150 Compact Bus Coupler from Beckhoff extends the Bus Terminal system with a PROFIBUS-DP interface in a space-saving and economical format. Designed to support up to 64 terminals—and expandable to 255 using a K-bus extension—it provides flexible modularity for distributed automation architectures. The coupler features automatic baud rate detection up to 12 Mbaud, ensuring seamless communication with various PROFIBUS masters without manual configuration. Its D-sub 9-pin connector with shielding guarantees stable signal transmission, while the integrated address switches simplify setup. With 128-byte input and output mapping, the BK3150 enables efficient data exchange for both digital and analog I/O modules. The compact IP20 housing and -25°C to +60°C operating range make it suitable for control cabinet installations and industrial environments demanding high reliability.
Key Features:
- Compact PROFIBUS Coupler: Connects Beckhoff Bus Terminals directly to PROFIBUS-DP networks in a small housing.
- Automatic Baud Rate Detection: Supports data rates up to 12 Mbaud for flexible and fast fieldbus communication.
- Modular Expansion: Accommodates up to 64 terminals, expandable to 255 with K-bus extension modules.
- High I/O Capacity: Handles up to 128 bytes each of input and output data for complex automation systems.
- Integrated Address Switches: Two rotary selectors simplify PROFIBUS station address configuration.
- Robust Electrical Isolation: 500 V isolation between power supply, fieldbus, and terminal bus for system safety.
- Reliable Power Distribution: 24 V DC power supply with up to 10 A through power contacts for connected terminals.
- Shielded Connection Interface: D-sub 9-pin PROFIBUS connector ensures stable and interference-free communication.
- Wide Temperature Range: Operates reliably between -25°C and +60°C, suitable for industrial control cabinets.
- Low Power Consumption: Efficient design with a 70 mA base current draw plus terminal load.
- Diagnostic Capability: Supports monitoring through TwinCAT and PROFIBUS diagnostic tools.
The BK3150 delivers the reliability and precision required for PROFIBUS-based automation systems, providing flexible connectivity, modular expansion, and efficient communication performance.
