This device has been replaced by the expanded successor model 57716
Like all models in the Web-IO Climate series, the Web-Thermograph Relay 57616 offers everything you need to connect a temperature sensor to the computer network. An alarm can be triggered when limits are violated directly from the integrated relay, so that signal lamps or acoustic warning signals can be turned on and off. In addition, the supply voltage in accordance with IEEE 802.3af (Power-over-Ethernet) can be provided over the network cable, with both phantom power over the data pairs as well as power over the unused wire pairs (for 10/100BT) is supported. Problems with receptacles, country-specific plug types, different line voltages etc. are 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.
