INSTRUCTIONS FOR ANALOGUE INPUTS:
The analogue inputs of this device are designed to measure
voltages/currents on floating circuits that is not electrically
connected to each other. It is also possible to measure
currents/voltages on non-floating circuits, with a potential
difference between negative terminals not exceeding
200 mV. In the case of measurement with thermocouples it
is possible to obtain correct measurements even if they are
applied to common metal parts.
The temperature measurement using thermocouples can be
affected by measurement errors due to the determination of
the cold junction temperature carried out near the terminal.
To eliminate any measurement errors it is necessary to wire
the thermocouples on an isothermal terminal board separate
from the device as shown in the diagram on the side.
Input No. 1 set as Pt100 (see the table on page 4) will then
be used to measure the cold junction temperature of said
terminal block.

FEATURE SUMMARY
THERMORESISTANCE
The relative dip-switch goes to the
OFF position.
Function valid only for analogue
input 1.
The product is not suitable for connection to a dangerous voltage conductor. The maximum allowable voltage is 50 Vac.
WARNING
The input for the RTD thermoresistance is available only for the first channel. For channels 2 to 8 it is not available.
