EK1100-0008 | EtherCAT Coupler with M8 connection

The EK1100-0008 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx). One station consists of an EK1100-0008 coupler, any number of EtherCAT Terminals and a bus end cap. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation. Compared with the EK1100, the EK1100-0008 has two M8 sockets, which are compatible with the EtherCAT Box modules.

The coupler is connected to the network via the upper Ethernet interface. The lower M8 socket may be used to connect further EtherCAT devices in the same strand. In the EtherCAT network, the EK1100-0008 coupler can be installed anywhere in the Ethernet signal transfer section (100BASE-TX) – except directly at the switch. The coupler BK9000 (for K-bus components) is suitable for installation at the switch. If Ethernet cables with adequate performance are used, e.g. ZK1090-3131-1xxx, line lengths of 100 m are possible via M8.
