Jonction 2 ports BECKHOFF EK1122 EtherCAT

Description

Integrating physical segments within an industrial communication network requires robust hardware designed to handle high-speed data routing. The EK1122 2-port EtherCAT junction module enables flexible branching of EtherCAT topologies, allowing the deployment of star and tree networks directly within terminal blocks. This compact terminal interfaces seamlessly with standard EtherCAT Couplers and I/O segments, extending the physical reach and structural configuration of automated production systems.

Operating at a native communication rate of 100 Mbit/s, this junction terminal facilitates direct coupling between various EtherCAT stations using standard shielded Cat.5 Ethernet cables. Because the EK1122 routes standard EtherCAT frames dynamically, no complex configuration or manual IP addressing is required during setup. The module draws its operating power directly from the E-bus backplane, simplifying field wiring while maintaining low power consumption and microsecond-level signal propagation delay.

Features

• Supports the configuration of physical star topologies in industrial networks.
