1 Quick-Start/Commissioning
Just a few steps are required to start up your W&T Web-Ther-
mometer and to make it visible in your network.
Power-over-Ethernet
The Web-Thermometers are designed for use in PoE (Power-
over-Ethernet) environments in accordance with IEEE802.3af.
Power is provided by the network infrastructure using the RJ45
terminal. The devices support both phantom power using data
pairs as well as power feed using the unused wire pairs s.
Power Supply).
!Use of the Web-Thermometer is also possible in networks
without PoE power supply. In this case simply use an external
power supply attached to the screw terminal as described in
the chapter Power Supply. No additional congurations or settings
are necessary.
1.1 Connecting the sensor (#57713, #57714, #57715,
#57720)
IO-Port

8
Plug the sensor included in the scope of delivery into the 9-pin
IO terminal on the unit.
1.2 Connecting the PT100/PT1000 sensor (#57708,
#57725, #57707) and output conguration

The output of the Web-Thermograph Relay is switched inter-
nally using a relay contact (normally open). The consumer
is connected to the screw terminals 1 and 2. The maximum
switchable DC or AC voltage is 39V, with a maximum current
ow of 300mA.
The PT100 or PT1000 temperature sensor is connected to screw
terminals 3, 4, 5 and 6, whereby the wires of the same color
must lie adjacent to each other.
The incoming line to the PT100 4-wire sensor may be of
virtually any practical length.
Connecting a PT100 3-wire sensor:
When connecting a PT100 3-wire sensor the same-color wires
are connected to the terminals marked with the corresponding
colors. A jumper to the remaining free terminal is required for
the single wire.
Connecting a PT100 2-wire sensor:
When connecting a PT100 2-wire sensor, one wire is brought to
the red terminal and the other to the black terminal. Jumpers
must be placed here to the free terminals.
