EK1122-0008 | 2-port EtherCAT junction with M8 connection

The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star can be realised by using several EK1122-0008 or EK1122 units in a station. Individual devices or complete EtherCAT strands can be connected at the junction ports. Compared with the EK1122, the EK1122-0008 has two M8 sockets, which are compatible with the EtherCAT Box modules.

The EtherCAT junctions are connected via M8 sockets. Separate LEDs display the link and activity status. The Run LED indicates the status of the EK1122-0008. Through TwinCAT and other suitable EtherCAT masters the EK1122-0008 also supports coupling and uncoupling of EtherCAT strands during operation (Hot Connect). If Ethernet cables with adequate performance are used, e.g. ZK1090-3131-1xxx, line lengths of 100 m are possible via M8.
