4.4 Schematic Diagram - Galvanic Isolation
The following schematic diagrams illustrate the internal connection between
the different connectors. This gives you the chance to properly install the
device in accordance with the potential equalization concept of your plant.
Note:
The PE connection (potential equalization) of the device is done via
the DIN rail.
4.4.1 Galvanic Isolation of NT 50-xx-EN Devices
The device types NT 50-CC-EN, NT 50-CO-EN, NT 50-DN-EN and
NT 50-DN-EN has three galvanically isolated areas. The coupling to PE is
shown in the following figure and in the following table.
