Potentiometer Converter
Описание
1-channel isolated barrier, 24 V DC supply (Power Rail), Potentiometer input, Voltage output 0 V .. 5 V, Lead resistance compensation adjustment, Accuracy 0.05 %, Up to SIL 2 acc. to IEC 61508pa. 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 .. 5 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.
