PEPPERL+FUCHS Potentiometer Converter KFD2-PT2-Ex1 Intrinsic Safety Barriers Isolated Barriers K-System Signal Converters
Features :
• 1-channel isolated barrier
• 24 V DC supply (Power Rail)
• Potentiometer input
• Voltage output 0 V ... 10 V
• Lead resistance compensation adjustment
• Accuracy 0.05 %
• Up to SIL 2 acc. to IEC 61508
Function :
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.
