Bottom layer

Bottom layer 1:
Example for routing the bottom layer of a four-layer PCB
  • Keep 24 V Us power supply as close as possible to the EJ1100 coupler in order to avoid unnecessary antennas.
  • 0 V Us/Up and 24 V Us/Up should be routed at different layers.
  • 24 V Us should be galvanically separated from 24 V Up.
  • It is recommended to route the signals SGND, 0 V Us/Up and 24 V Us/Up as an area.

Layout for Up power supply

In the figure above, the areas for the Up supply are shown as an example. The actual layout must be adapted to the respective application.
