Information About BK2020
The BK2020 is part of Beckhoff’s Economy plus series, developed to interface the Lightbus system with Beckhoff’s modular Bus Terminals. It automatically identifies connected terminals and maps their input/output signals to the process image without manual configuration. The unit supports up to 255 distributed terminals with K-bus extension, ensuring scalable system design across large installations. With 2.5 Mbaud transfer rate and support for both plastic and HCS optical fibers, the BK2020 enables fast, interference-free communication ideal for modern industrial environments.
Key Features:
- Modular Expansion: Supports up to 64 terminals or 255 with K-bus extension for flexible I/O configurations.
- High Signal Processing: Handles up to 1,020 digital and 128 analog channels per slave.
- Auto-Configuration: Detects and assigns terminal data automatically for simplified setup.
- High-Speed Data Transmission: Operates at 2.5 Mbaud over optical fiber for rapid communication.
- Reliable Connectivity: Uses standard fiber-optic connectors (Z1000/Z1010) compatible with plastic or HCS fiber.
- Efficient Power Handling: Supplies 24 V DC with 1,750 mA K-bus current and 10 A power contacts.
- Electrical Isolation: 500 V isolation ensures safe separation of control and power circuits.
- Durable Operation: Functions reliably in environments from 0 to 55°C with high humidity resistance.
The BK2020 delivers the reliability and precision required for distributed control systems and industrial automation networks.
