The EK1101-0008 has two M8 sockets. The upper Ethernet interface is used to connect the coupler to the network; the lower socket

serves for the optional connection of further EtherCAT devices in the same segment. The M8 socket is compatible with the EtherCAT

Box modules and therefore enables uniform cabling in the IP20 and IP67 range. A group of EtherCAT components can be assigned

a unique ID via the hexadecimal ID switches. This group can then be located at any position within the EtherCAT network. Variable

topologies are therefore easily implementable. In addition, an EtherCAT junction or an EtherCAT extension can be used for the

extension or for setting up a line or star topology.

The system and field supply, each 24 V DC, is provided directly at the coupler. The attached EtherCAT Terminals are supplied with

the current required for communication from the supplied system voltage. The coupler can supply a maximum of 5 V and 2 A. If

higher current is required, power feed terminals such as the EL9410 have to be integrated. The field supply is forwarded to the

individual I/O components via the power contacts with up to 10 A.
