EtherCAT coupler EK1100-0008 (M8 connection)
The EK1100-0008 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx/ESxxxx). One station
consists of a coupler EK1100-0008, any number of EtherCAT Terminals and a bus end terminal.
The coupler converts the telegrams from Ethernet 100BASE-TX to E-bus signal representation. Compared to
EK1100 the EK1100-0008 has two M8 sockets instead of two RJ45 sockets, compatible to the ones of the
EtherCAT-Boxes.
The upper Ethernet interface is used to connect the coupler to the network; the lower M8 socket serves for
the optional connection of further EtherCAT devices in the same strand.
The coupler supplies the connected terminals with the necessary E-bus current for communication. The
coupler can supply a maximum of 5V/2A. Power feed terminals (e.g. EL9410) must be integrated if more
current is required.
In the EtherCAT network, the EK1100-0008 coupler can be installed anywhere in the Ethernet signal transfer
section (100BASE-TX) except onto the switch directly. By using respective powerful Ethernet cables e.g.
ZK1090-3131-1xxx distances of 100m are also possible via M8.
