EP1122-0001 | 2-port EtherCAT junction


The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star can be realised by using several EP1122 units in a station. Individual devices or complete EtherCAT strands can be connected at the junction ports. The EtherCAT junctions are connected via shielded M8 screw connectors with direct display of link and activity status. The Run LED indicates the status of the EP1122. Through TwinCAT and other suitable EtherCAT masters the EP1122 also supports coupling and uncoupling of EtherCAT strands during operation (Hot Connect).
