EP1122-0001 | EtherCAT Box, 2-port junction, M8
Cables overview
The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star can be realized by using several EP1122-0001 units in a station. Individual devices or complete EtherCAT strands can be connected at the junction ports. The EtherCAT junctions are connected via M8 sockets with direct display of link and activity status. The Run LED indicates the status of the EP1122-0001. Through TwinCAT and other suitable EtherCAT masters the EP1122-0001 also supports coupling and uncoupling of EtherCAT strands during operation (Hot Connect).
