The Beckhoff CU EtherCAT Junctions series is designed to branch and distribute EtherCAT communication across multiple network segments within an automation system.
The series includes junction and hub variants with multiple RJ45 ports, including standard and extended-distance versions, to support flexible EtherCAT topology design. These units are used to split one EtherCAT line into several downstream branches while maintaining integration within the EtherCAT system architecture. The series also provides status indication through diagnostic LEDs and supports commissioning through the TwinCAT environment and standard EtherCAT configuration procedures. Overall, the CU EtherCAT Junctions are intended for control systems that need compact EtherCAT distribution components for structured cabling, multi-branch layouts, and scalable network expansion.
