The following schematic diagram illustrates the internal connection between

the different connectors. This gives you the possibility 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 two bottom screw holes.

Figure 8: Galvanic Isolation NB 100 RE-DP Device

The device has three galvanically isolated areas

System area, galvanically coupled with the power supply connection

Ethernet connecting area, 2 * M12 D coded. Both Ethernet ports are

galvanically isolated against each other.

Fieldbus connecting area, M12 male and female connector A or B

coded. The pins are connected to each other internally.

The following table shows the characteristics of the galvanic isolation of the

different areas and coupling against potential equalization.
