Function

Tia3 temperature converters are aimed at converting signals coming from large panel of input signals:• Coversion of temperature measurement with RTD100, RTD1000, Ni100, Ni1000 or thermocouple.• Conversion of linear resistance variation (from level sensors or valves).• Voltage (mV) and ohmic measurement.DIN rail mountingCertified to be installed in explosive atmosphere (see codification).
