Product Description P/N: BK1250
Description
The Beckhoff BK1250 is an EtherCAT Bus Coupler designed to support mixed operation of EtherCAT Terminals (ELxxxx) and standard Bus Terminals (KLxxxx) within a single station. Operating at 100 Mbaud and powered by a 24 VDC supply, it provides fast data exchange and compact integration for modular automation architectures. With its lightweight design and rail-mount construction, the BK1250 offers a cost-effective solution for flexible distributed I/O systems.

Information About BK1250
The BK1250 is part of Beckhoff’s EK1xxx EtherCAT coupler series, engineered for installations requiring both EtherCAT and K-bus terminal technologies. Its terminal-housing format eliminates the need for additional cabling, providing a streamlined and compact integration into DIN rail–mounted control panels. Compatible with up to 64 directly connected Bus Terminals—and expandable to 255 via K-bus extension—it enables high-density I/O configurations for modern automation systems. Designed for smooth integration with Beckhoff TwinCAT, ADS configuration via KS2000, and PLC-based parameterization, the BK1250 ensures reliable data exchange, safe protective-earth handling, and efficient power distribution in industrial applications.
Key Features:
- Mixed terminal support: Allows simultaneous use of EtherCAT (EL) and standard Bus Terminals (KL).
- High-speed communication: 100 Mbaud transfer rate ensures rapid process updates.
- DIN rail installation: Compact 35 mm rail mounting for space-efficient panel layouts.
- Integrated power distribution: 24 VDC system and field supply with up to 10 A via power contacts.
- Automatic process image assignment: Simplifies configuration in EtherCAT systems.
- Expanded terminal capacity: Supports 64 Bus Terminals, expandable to 255 via K-bus extension.
- Robust protection: Includes a protective earth power contact capable of grounding up to 125 A short-circuit current.
The BK1250 delivers the reliability and modular flexibility required for advanced distributed I/O and mixed bus architectures.
