The Beckhoff EK1122 2-Port EtherCAT Junction is a compact and versatile module designed to simplify the expansion and structuring of EtherCAT networks. By offering two additional ports, the EK1122 allows users to create flexible system topologies, including star, line, and tree structures, while maintaining EtherCAT’s hallmark performance and determinism.

At its core, the EK1122 is used for the coupling of EtherCAT junctions. This makes it ideal for building modular and scalable network architectures, especially in complex automation environments where multiple devices and subsystems need to be integrated efficiently. Its support for Ethernet/EtherCAT Cat.5 shielded cables ensures robust and noise-resistant communication, with station distances of up to 100 m (100BASE-TX) between devices.

Despite adding flexibility to network design, the EK1122 introduces virtually no latency, with a signal delay of only about 1 µs. This ensures that cycle times remain fast and deterministic, supporting real-time communication across large and distributed systems. With 100 Mbit/s transfer rates, the junction fully preserves EtherCAT’s high-speed communication performance, even in networks with many interconnected nodes.

Installation and commissioning of the EK1122 are straightforward. As a plug-and-play device, it requires no configuration, reducing engineering effort and enabling rapid deployment. The module automatically integrates into the EtherCAT system, making it a practical solution for dynamic or evolving networks where new nodes and branches may be added as the system grows.

Designed for durability and reliability, the EK1122 is well suited for use in industrial environments where robustness and continuous operation are essential. Its compact form factor ensures that it can be installed easily within control cabinets, conserving space while offering significant flexibility in network architecture.

The EK1122 finds applications across a wide range of industries. In machine automation, it enables distributed star topologies for connecting subsystems or modular machine sections. In process automation, it allows efficient branching to distributed sensors and actuators across large plants. In building automation, it provides reliable connections to distributed controllers, lighting, and HVAC systems.

In summary, the Beckhoff EK1122 EtherCAT Junction is a powerful and easy-to-use solution for extending and structuring EtherCAT networks. With two additional ports, high-speed 100 Mbit/s communication, minimal delay, and plug-and-play integration, it combines flexibility with performance, enabling engineers to design scalable, efficient, and reliable EtherCAT systems for modern automation environments.
