Universal measurement transducers
Universal measurement transducers for temperature, standard and potentiometer signals
The ACT20X-HUI-SAO-S is a universal input signal isolator/converter. This model processes temperature
signals from PT100 sensors and thermocouples as well as DC voltage and current signals (mA) from the
hazardous area. On the output side, an isolated milliamp signal is passed to the receiver or controller in the
safe area. This model also has a relay output which can be used for a process alarm or trip.
EX area Zone 0, 1, 2, 20, 21, 22 Safe area Zone 2 / FM Class 1, Division 2
