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 0 V ... 10 V voltage output (consistant with 0 mA ... 20mA current output, see for example KFD2-PT2-Ex1-4).
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.
