EK1101 | EtherCAT Coupler with ID switch

The EK1101 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx). A station consists of an EK1101 coupler, any number of EtherCAT Terminals, an EL9011 bus end cap or an EK1110 EtherCAT extension. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation.

The EK1101 has three hexadecimal ID switches for assigning an ID to a group of EtherCAT components. This group can then be located at any position within the EtherCAT network. Variable topologies are therefore easily implementable.
