ENQUIRE NOWProduct Overview
The Pepperl+Fuchs KFD2-UT2-Ex1 is a 1-channel isolated barrier universal temperature converter. It accepts thermocouple, RTD, potentiometer or millivolt inputs from the hazardous area and converts them into a 0/4 … 20 mA current output for PLC, DCS or recorder inputs.
The output can operate in sink or source mode, and line fault and sensor burnout detection drive a NAMUR NE43 fault signal. The module is configured with PACTware, supplied at 24 V DC via the Power Rail or terminals, and suitable for applications up to SIL 2 to IEC/EN 61508 / IEC/EN 61511.
