Available. The Beckhoff EP1122-0001 is a 2-port EtherCAT junction module designed to facilitate the configuration of EtherCAT star topologies. By integrating multiple EP1122-0001 units within a single station, users can establish a modular EtherCAT star network. This module allows individual devices or entire EtherCAT segments to be connected at its junction ports. The EP1122-0001 features shielded M8 sockets that provide direct indicators for link and activity status, with a Run LED displaying the module's operational status. Additionally, it supports the coupling and uncoupling of EtherCAT segments during operation (Hot Connect) when used with TwinCAT or other compatible EtherCAT masters. The module operates at a nominal voltage of 24 V DC, with a tolerance range of -15% to +20%, and supports data transfer rates up to 100 Mbit/s over distances of up to 100 meters using 100BASE-TX cables. Its rugged PA6 (polyamide) housing ensures durability in industrial environments, and it conforms to protection classes IP65, IP66, and IP67, as per EN 60529 standards. The EP1122-0001 is also compliant with EMC immunity and emission standards EN 61000-6-2 and EN 61000-6-4, and has received approvals including CE, UL, ATEX, and IECEx.
