Beckhoff Automation LLC EJ1100 | EtherCAT plug-in module, EtherCAT Coupler, RJ45

The EJ1100 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the EtherCAT plug-in modules. The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation. A module station consists of a coupler and any number of EtherCAT plug-in modules, which are automatically detected and individually displayed in the process image. Special features: connection technology 2 x RJ45 socket connection lengths up to 100 m The EJ1100 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. The coupler supplies the attached plug-in modules with the current required for communication. The coupler can supply a maximum of 3.3 V and 2.2 A.
