W&T
PoE supply
The Web-IO Analog-In/Out can be used in PoE (Power-over-
Ethernet) environments in accordance with IEEE802.3af. The
supply voltage is provided then by the network infrastructure
through the RJ45 terminal. The device supports both phantom
power using data pairs 1/2 and 3/6 as well as power on the
unused wire pairs 4/5 and 7/8.
To enable power management for the supplying components,
the W&T Web-IO Analog-In/Out is identified as a Power Class 1
device with a power consumption of 0.44 to 3.8W.
As an alternative to PoE the device can also be powered
externally using the screw terminal located on the underside of
the device.

Use of the W&T Web-IO Analog-In/Out is also possible in
networks wihtout PoE. In this case simply use an external
power supply with the screw terminals as described
above. No additional configurations or settings are necessary.
