The Pepperl+Fuchs KFD2-UT2-Ex1 is a 1-channel isolated barrier designed for temperature signal conversion in hazardous area applications. It safely transfers signals from temperature sensors such as RTDs and thermocouples from Ex zones to safe areas while maintaining full galvanic isolation between input, output, and power supply circuits.
Powered via a 24 V DC supply using the Pepperl+Fuchs Power Rail system, the KFD2-UT2-Ex1 enables efficient installation and reduced wiring complexity within control panels. Its universal input capability allows connection to a wide range of temperature sensor types, providing flexibility across different process applications.
The unit converts temperature signals into a standard analogue 4–20 mA output for seamless integration into PLC and DCS systems. Its compact DIN rail design and reliable performance make it ideal for use in industries such as oil & gas, chemical processing, and energy where accurate temperature monitoring and intrinsic safety are essential.
