EK1101-0008 | EtherCAT Coupler with ID switch and M8 connection

The EK1101-0008 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx). Compared with the EK1101, the EK1101-0008 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. If Ethernet cables with adequate performance are used, e.g. ZK1090-3131-1xxx, line lengths of 100 m are possible via M8.

The EK1101-0008 has three hexadecimal ID switches for assigning an ID to a group of EtherCAT components. This group can then be located at any position within the EtherCAT network. Variable topologies are therefore easily implementable.
