The EK1828-0010 has two RJ45 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. 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 1 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.
