Beckhoff Automation EtherCAT Terminal EK1100 EK1122

Beckhoff Automation EtherCAT Terminal EK1100 EK1122

EK1122 | 2-port EtherCAT junctionPreferred type

EK1122 | 2-port EtherCAT junction

The EK1122 2-port EtherCAT junction can be used in an EtherCAT Terminal segment at any desired position between the EtherCAT Terminals and enables configuration of EtherCAT star topologies.

A modular EtherCAT star hub can be realized by using several EK1122 units in a station.

Special features:

Connection technology: 2 x RJ45 sockets

Connection lengths: up to 100 m

Can be used for configuring an EtherCAT star topology

The EK1122 has two RJ45 sockets, which enable connection of an Ethernet cable with RJ45 connector and establish a connection to a further EtherCAT segment or to individual EtherCAT devices.

The EK1122 supports coupling and uncoupling of EtherCAT segments during operation (Hot Connect).
