Connectors for the power supply of the SCALANCE W786
Possible power supplies
The following power supplies are suitable for the SCALANCE W786:
●
48 VDC direct voltage
Use the two-pin connector supplied with the SCALANCE W786.
●
12 - 24 VDC direct voltage
Use the power supply adapter 12 - 24 VDC available as an accessory.
●
100 - 240 VDC direct voltage
Use the power supply adapter 100 - 240 VDC available as an accessory.
●
Power over Ethernet (PoE, only with the RJ-45 variants)
If an eight-wire Ethernet cable is used, it is possible to supply power over the four wires
that are not used as data lines. As an alternative, the voltage can be modulated onto the
data lines ("phantom power").
If a Fast Connect Ethernet connector is used to allow cable assembly in the field and due
to its greater mechanical strength, you can only use four-wire cables. In this case, only
phantom power is possible. This does not represent a restriction for the user because
PoE-compatible power equipment always provides both options.
