Description
Line, tree or star – EtherCAT supports almost any topology. The 3-port CU1123 EtherCAT junction provides a compact solutions to cascade an EtherCAT network. Where junctions with several ports need to be implemented outside of the EtherCAT Terminal system, the DIN rail-mountable EtherCAT junction can be used instead of the EK1122 EtherCAT Coupler and the 8-port CU1128 EtherCAT junction. Port 1 is the input port for the EtherCAT network; ports 2, and 3 can be used to connect additional EK1100 Couplers or EtherCAT Box modules. The EtherCAT branches are connected via RJ45 ports featuring link and activity status indicators.
