EK1818 EtherCAT Coupler with integrated digital inputs/outputs
The EK1818 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the EtherCAT Terminals. In addition, eight digital inputs and four digital outputs are integrated. The resulting design is particularly suitable for applications with a small number of I/Os. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation. A station consists of a coupler and any number of EtherCAT Terminals that are automatically detected and individually displayed in the process image.
