Pepperl Fuchs KFD2-PT2-Ex1-5 Potentiometer Converter (70177763)

The P&F KFD2-PT2-Ex1-5 is a high-accuracy potentiometer converter designed for intrinsic safety applications. Accepting 3-, 4-, or 5-wire potentiometer inputs from hazardous areas, it outputs a standard 4 … 20 mA signal with 0.05% accuracy. It compensates for lead resistance up to 5% and supports configurations through built-in potentiometers, making it ideal for precision position sensing in process automation.
