Product Description
BECKHOFF EK1122 2 Port EtherCAT Junction Module
The Beckhoff EK1122 2-port EtherCAT junction module enables the flexible creation of EtherCAT star, tree, and line topologies within industrial automation networks. Seamlessly integrating into the EtherCAT Terminal segment via internal E-bus connections, the module provides two standard RJ45 ports (X1 and X2) supporting 100BASE-TX Ethernet transmissions over distances up to 100 meters per channel. With rapid diagnostics provided by integrated Run and Link/Activity LEDs, ATEX II 3G certification for hazardous locations, and UL listing, the EK1122 is an essential building block for modular machine designs and distributed I/O architectures.
