Pepperl+Fuchs KFD2-UT2-Ex1 Universal Temperature Converter

This Pepperl+Fuchs KFD2-UT2-Ex1 Universal Temperature Converter / Isolated Barrier is used for intrinsically safe applications. It is designed to connect RTDs, thermocouples, or potentiometers in the hazardous area, and provide a proportional 0/4 mA-20 mA signal to the safe area.

• 1-channel isolated barrier
• 24 V DC supply (Power Rail)
• TC, RTD, potentiometer or voltage input
• Current output 0/4 mA-20 mA
• Sink or source mode
• Configurable by PACTware
• Line fault (LFD) and sensor burnout detection
• Up to SIL2 acc. to IEC 61508

The barrier offers 3-port isolation between input, output, and power supply. A removable terminal block K-CJC-** is available for thermocouples when internal cold junction compensation is desired and fault is indicated by a red flashing LED per NAMUR NE44 and user-configured fault outputs. The unit is easily programmed with the PACTware configuration software and a collective error messaging feature is available when used with the Power Rail system.
