EJ1122 2-port EtherCAT junction
The EJ1122 2-port EtherCAT junction can be positioned in an EtherCAT module segment anywhere between the EtherCAT plug-in modules and enables configuration of EtherCAT star topologies. A modular EtherCAT star hub can be realized by using several EJ1122 on one signal distribution board.
