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.
