Information About BK2000
The BK2000 is part of Beckhoff’s Bus Coupler family and serves as a communication bridge between the Lightbus system and modular Beckhoff I/O terminals. It enables flexible system expansion by supporting up to 64 terminals, with automatic input/output mapping to the process image for simplified configuration. The unit employs fiber optic transmission, using APF or HCS fibers for long-distance communication—up to 300 meters—ensuring high-speed and noise-immune data transfer. With a data rate of 2.5 Mbaud and optimized telegram structure, the BK2000 achieves transmission times as fast as 25 µs for 32-bit data exchange. This makes it ideal for time-critical industrial automation environments that demand precision, safety, and modular expandability.
Key Features:
- High-Speed Lightbus Communication: Operates at 2.5 Mbaud for rapid data exchange between field devices and control systems.
- Modular Expansion: Supports up to 64 terminals (512 digital I/Os and 128 analog I/Os) for scalable automation setups.
- Automatic Configuration: Recognizes connected terminals and maps inputs/outputs automatically to the process image.
- Fiber Optic Connectivity: Uses APF or HCS fibers for reliable long-distance and interference-free data transmission.
- Flexible Station Distances: Supports 45 m with plastic fibers and up to 300 m with HCS fibers between stations.
- Strong Power Handling: 24 VDC operation with 10 A power contacts ensures stable and efficient energy distribution.
- Robust Electrical Isolation: 500 V isolation enhances system safety and signal integrity.
- Industrial Reliability: IP20-rated, DIN-rail mountable design with CE compliance ensures long-term stable performance.
The BK2000 delivers the reliability and precision required for Lightbus-based automation systems, distributed I/O control, and modular industrial communication networks.
