KFD2-PT2-EX1-5, Potentiometer Converter

Potentiometer Converter, KFD2-PT2-EX1-5 1-channel isolated barrier 24 V DC supply (Power Rail) Potentiometer input Current output 4 mA ... 20 mA Lead resistance compensation adjustment Accuracy 0.05 % Up to SIL 2 acc. to IEC/EN 61508 This isolated barrier is used for intrinsic safety applications. It provides the source voltage to a potentiometer and transfers its wiper position from hazardous areas to safe areas. It then converts the signal to a 4 mA ... 20mA current output. The unit can be used in a 3-, 4-, or 5-wire configuration depending on the required measurement accuracy. Terminals 2 and 5 are used as the sense line for the potentiometer lead resistance compensation in a 5-wire configuration. The barrier’s potentiometer can be used to compensate for lead resistance up to 5 % of the hazardous area potentiometer value.   Download the complete datasheet as a PDF
