EK1122-0008
The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star
hub can be realized by using several EK1122 units in a station. Individual devices or complete EtherCAT
strands can be connected at the junction ports. Compared to EK1122 the EK1122-0008 has two M8 sockets
compatible to the two RJ45 sockets instead. The EtherCAT junctions are connected via M8 sockets. The link
and activity status is indicated by separate LEDs at the front. The Run LED indicates the status of the
EK1122. With TwinCAT and other appropriate EtherCAT Masters the EK1122-0008 supports coupling and
uncoupling of EtherCAT strands during operation (hot connect).
By using respective powerful Ethernet cables e.g. ZK1090-3131-1xxx distances of 100m are also possible
via M8.
