Background information:
Like all the Web-IO Climate series models, the Web-Thermograph NTC PoE 57614 offers everything you need for connecting a temperature sensor to the computer network. In addition, the power can be provided per IEEE 802.3af (Power-over-Ethernet) over the network cable, with both phantom power over the data pairs as well as power using the wire pairs not used for 10/100BT. Problems with outlets, country-specific plug types, various AC voltages etc. are now a thing of the past.

For cases in which PoE is planned but not yet fully implemented, it is also possible to provide power using an external power supply and screw terminals.
