EK1110-0043 | EtherCAT EJ coupler, CX and EL terminal connection

The EK1110-0043 EtherCAT EJ coupler connects the compact DIN rail PCs from the CX series and attached EL terminals to the EJ modules on an application-specific PCB (signal distribution board). The E-bus signals and the supply voltage UP from the field side are forwarded directly to the PCB via a plug connector on the rear side of the EtherCAT EJ coupler. The direct connection between Embedded PC, EL terminals and the EJ modules via the PCB means that neither an EtherCAT extension (EK1110) nor an EtherCAT Coupler (EJ1100) is required. The Embedded PC can be expanded by EtherCAT Terminals that, for example, are not yet available in the EJ system. The pre-assembled subsystem, which consists of a DIN rail including Embedded PC and EtherCAT plug-in modules mounted on the PCB, can be tested in advance and integrated optimally as a complete unit into the assembly of the produced machine at a later time. The EK1110-0043 is supplied with power by the power supply unit of the Embedded PC. The supply of power to the E-bus signals (UE-bus) and the power contacts (UP) is signalled via diagnostic LEDs.
