This isolated signal conditioner is a loop-powered isolator that converts the resistance from a 3-wire RTD to a 4 mA ... 20mA signal and provides isolation for non-intrinsically safe applications. A selectable analog linearization ensures a temperature linear 4 mA ... 20mA output between 25 °C ... 375 °C. It also features conveniently located DIP switches and potentiometers to make field calibration easy.
