Use of U_S/ U_P of the coupler

The outfeed of the coupler comes from the EtherCAT P signal input (X1). In addition, the coupler is powered by this U_S voltage.

The connections for the supply of U_S/ U_P can be used for the supply of the power contacts. To do this, jumpers from the output terminal points e.g. terminal point 1 and 5 for U_S or terminal point 4 and 8 for U_P) must be placed on the infeed (terminal point 2/ 3 and 6/ 7). The bridges should be as short as possible.

As a result, the supply of the following terminals, which are fed from the power contacts realized. Usually, the input modules are supplied from U_S and output modules from U_P. If the outputs are to be switched off separately, the outfeed U_P of the coupler can be connected via a switch (S) to the infeed to supply output modules. A separate potential supply terminal EL9110 can also be used as an infeed (see following illustration).
