Power
Switching power supply with extended range
24…230 Vac/dc ±15% 50/60Hz – 5,5VA.
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 10 and 12
• When shielded cable is used, it should be
grounded at one side only to avoid ground loop
currents

3
For thermoresistances NTC, PTC, PT500,
PT1000 e potentiometers
• 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 to avoid ground loop
currents
