Beckhoff: EtherCAT EJ Coupler, CX and EL Terminal Connection, EtherCAT Junction

January 20, 2021

The EK1110-0044 EtherCAT EJ Coupler connects the compact Embedded PCs from the CX series and the attached EtherCAT Terminals with the EtherCAT plug-in modules on an application-specific circuit board (signal distribution board).

Special features:

  •    –   Connection technology: 1 x connector at the rear of the EtherCAT EJ Coupler, 1 x RJ45 socket
  •    –   Forwarding of E-bus signals and field supply to the signal distribution board
  •    –   additional EtherCAT junction

The E-bus signals and the supply voltage of the field side UP are routed directly to the signal distribution board via a plug connector at the rear of the EtherCAT EJ Coupler. Thanks to the direct coupling of the Embedded PC and EtherCAT terminals with the EtherCAT plug-in modules on the PCB, no EtherCAT extension (EK1110) or EtherCAT Coupler (EJ1100) is required. The system and field supply of the EK1110-0044 is provided by the power supply unit of the Embedded PC. In addition, the EK1110-0044 has an RJ45 socket that enables connection of an Ethernet cable with RJ45 connector and establishes a connection to a further EtherCAT segment or to individual EtherCAT devices.

The Embedded PC can be extended with EtherCAT Terminals that are not yet available in the EJ system, for example. The pre-assembled subsystem, consisting of a printed circuit board with mounted DIN rail, Embedded PC and EtherCAT plug-in modules, can be tested in advance and subsequently integrated into the machine assembly as a complete unit.
