Introduction
EK1100-0008 EtherCAT coupler (M8 connection)
The EK1100-0008 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx/ESxxxx). One station consists of an EK1100-0008 coupler, any number of EtherCAT Terminals and a bus end terminal. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation. Instead of the two RJ45 sockets as in the EK1100, the EK1100-0008 has two M8 sockets that are compatible with 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 5 V/2 A. 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 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.
