Universal measurement transducers
Output -powered universal measurement transducers
The ACT20X-HUI-SAO-LP is a universal input, isolating signal converter. This model processes temperature
signals from PT100 sensors and thermocouples as well as DC voltage and current signals (mA) from the
hazardous area. The 12.5 mm wide module is powered through it‘s 4-20 mA output.
