I/Os and fieldbus systems
Beckhoff EK1xxx BK1xx0 EtherCAT Couplers
The EtherCAT Couplers are the link between the EtherCAT protocol at fieldbus level and the EtherCAT Terminals. Since communication in the EtherCAT system is continuous through to the last terminal, the coupler only converts the physical layer without changing the process data stream.

There is a selection of three different technologies:
A distinction is made between a coupler, a junction and an extension. The EtherCAT Coupler is the head station with which the terminal segment starts. The junction can be placed anywhere in the EtherCAT segment and thus allows the setup of a star topology. The extension is plugged into the end of the EtherCAT terminal block and allows a setup with a line topology.
The products are available in different versions, depending on the required physical layer and additional functions.
