Pepperl Fuchs KFD2-UT2-Ex2 Universal Temperature Converter (248767)
The P&F KFD2-UT2-Ex2 is a dual-channel isolated barrier that converts thermocouple, RTD, voltage, or potentiometer signals into proportional analog current outputs. Designed for hazardous areas, this unit features two configurable outputs and can function as a signal splitter (1 input to 2 outputs). Ideal for intrinsic safety applications, it is fully programmable via PACTware and includes SIL 2 compliance, line fault detection, and cold junction compensation support.
