Product Description
CU1128 is a Beckhoff junction in the CU EtherCAT Junctions series. It uses the EtherCAT protocol and provides eight RJ45 bus interfaces for distributing an EtherCAT network among multiple segments. The interfaces transfer data at 100 Mbit/s and support station distances of up to 100 m. Connections require shielded cable rated Cat.5 or higher; the shielding helps reduce electromagnetic interference during data transmission. Distributed Clocks support enables synchronized timing across connected EtherCAT devices, while Hot Connect support allows predefined network sections to be connected or disconnected during operation.
The junction operates from a 24 V DC supply. Its three-pin power connection provides positive, negative, and protective-earth terminals. The CU1128 mounts on a 35 mm rail and measures 100 mm in height, 122 mm in width, and 38 mm in depth. Its IP20 protection rating guards against contact with fingers and similarly sized solid objects but does not provide water protection. The unit supports a maximum relative humidity of 95%.
