Connection of CX and EL terminals via the EK1110-004x EtherCAT EJ Coupler
The EK1110-0043 and EK1110-0044 EtherCAT EJ couplers connect the compact DIN-rail PCs of the CX
series and attached EtherCAT terminals (ELxxxx) with the EJ modules on the signal distribution board.
The EK1110-004x are supplied from the power supply unit of the Embedded PC.
The E-bus signals and the supply voltage of the field side U are routed directly to the PCB via a plug
P
connector at the rear of the EtherCAT EJ couplers.
Due to the direct coupling of the Embedded PC and the EL terminals with the EJ modules on the PCB, no
EtherCAT extension (EK1110) or EtherCAT coupler (EJ1100) is required.
The Embedded PC can be expanded with EtherCAT terminals that are not yet available in the EJ system,
for example.
