Pepperl Fuchs KFD0-TR-1 Datasheet

RTD Converter

KFD0-TR-1

<1-channel signal conditioner

<24 V DC supply (loop powered)

<2- or 3-wire Pt100 RTD input

<Output 4 mA ... 20 mA, temperature linearization selectable

<DIP switch selectable ranges

<Sensor breakage detection

Function

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.
