The Beckhoff BK1150 is a compact and efficient Bus Coupler designed to seamlessly integrate the EtherCAT real-time Ethernet system with modular, extendable KL/KS electronic terminal blocks at the fieldbus level. This unit is capable of supporting up to 64 terminals, with the potential to extend to 255 terminals using the K-bus extension. The BK1150 automatically recognises connected Bus Terminals and allocates them into the EtherCAT process image, ensuring smooth and reliable operation.

Housed in a space-saving IP 20 enclosure, the BK1150 is approximately 5 mm narrower than its predecessor, the BK1120, making it an ideal choice for installations where space is at a premium. The device features two RJ45 interfaces for easy connection to the EtherCAT network and additional devices. It operates on a 24 V DC power supply and supports a maximum data transfer rate of 100 Mbaud, with a typical data transfer time of 0.01 ms for 10 modules with 32-bit inputs and outputs.

The BK1150 offers flexible configuration options via the KS2000 software or EtherCAT (ADS), allowing for tailored setups to meet specific application requirements. With its robust design and versatile functionality, the Beckhoff BK1150 is a reliable choice for industrial automation systems seeking to leverage the benefits of EtherCAT technology.
