It is a precision grade transducer is used for galvanically isolated measurement of Temperature using external PT100 (RTD) Sensor 3 Wire Type. It measures temperature by measuring resistance of the PT100 Sensor. The input is in the form of Resistance and provides a Stable, Ripple-Free and Optically Isolated DC load independent output in the form of current or voltage. The transducer is fully solid state. Use of latest circuit techniques and quality components ensure reliable operation over long period.
