AN1 Analogue Input
For thermocouples K, S, R, J.
• Comply with polarity.
• For possible extensions, use a compensated wire
and terminals suitable for the thermocouples used
(compensated).
• When shielded cable is used, it should be grounded at
one side only.

For thermoresistances PT100, NI100.
• For the three-wire connection use wires with the same
section.
• For the two-wire connection short-circuit terminals 1
and 3.
• When shielded cable is used, it should be grounded at
one side only.
• Select internal jumper
JP3
as in the fi gure.
For thermoresistances NTC, PTC, PT500, PT1000 e poten-
tiometers.
When shielded cable is used, it should be grounded at one
side only to avoid ground loop currents.
For linear signals V / mA.
• Comply with polarity.
• When shielded cable is used, it should be grounded at
one side only.
• Select internal jumper JP3 as in the fi gure.
If jumpers are not properly selected, 12 Vdc /
30 mA are not available on terminal 3 to
power the sensor.
