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
flow 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.
