5.2.2.1 RTD
For supported sensors see Tab. 3.2.
The RTD sensor should be connected to an input using a three-wire line in order to reduce the influence of
the resistance of the lead wires on the measurement results.
Fig. 5.4 RTD wiring
5.2.2.2 TC
For supported sensors see Tab. 3.2.
NOTICE
Only thermocouples with insulated (ungrounded) measuring („hot“) junction can be used,
because the negative terminals AIn-1 of all inputs have the same electric potential.
Fig. 5.5 TC wiring
To connect a remote thermocouple to the input, use thermocouple (compensating) cable.
About using of cold junction compensation (CJC) see Sect. 4.8.7.
5.2.2.3 Current or voltage active linear signals
For supported signals see Tab. 3.2.
Active sensors use external DC voltage source.
NOTICE
The negative terminals of all inputs AIn have the same electric potential.
Fig. 5.6 Voltage sensor wiring (3-wire)
Before connecting a current sensor to the selected input, turn the DIP switch of this input to “1” position (Fig.
2.4).
Turn the DIP switch in “0” position when using a non-current sensor. Otherwise the measured values will be
calculated incorrectly.
