Pepperl Fuchs KFD2-UT2-Ex1 Universal Temperature Converter (248764)

The P&F KFD2-UT2-Ex1 is a 1-channel isolated barrier designed for safe and efficient temperature signal transmission in hazardous areas. Accepting input from thermocouples, RTDs, voltage, or potentiometers, it provides an isolated 0/4 mA to 20 mA output in sink or source mode. The unit is easily configured via PACTware software and supports line fault detection, sensor burnout detection, and is certified up to SIL 2 per IEC 61508/61511.
