The Pepperl + Fuchs KFD2-UT-EX1 is a versatile signal converter designed to facilitate the connection of temperature sensors such as RTDs (Pt100, Ni100) and thermocouples (types B, E, J, K, L, N, R, S, or T) in hazardous areas. This single-channel unit is engineered to provide a reliable 4-20mA output, with an optional 1-5V output available. It boasts a 24V DC nominal power supply and offers exceptional accuracy within ±0.1%.
The KFD2-UT-EX1 is equipped with a range of adjustment options, allowing for precise calibration of temperature measuring ranges for resistance and voltage sensors. It supports 2-, 3-, or 4-wire configurations for RTDs and offers both internal and external cold junction compensation for thermocouples. Additionally, the device includes sensor burnout monitoring for thermocouples and sensor burnout and short-circuit monitoring for Pt100 sensors.
All settings on the KFD2-UT-EX1 can be configured via a serial interface to a PC, enabling online parameterisation for ease of use. The device can be factory set upon request, ensuring it is ready for immediate deployment in your system. The signal converter is also compliant with NAMUR NE 21 standards for electromagnetic compatibility, ensuring stable operation in industrial environments.
The KFD2-UT-EX1's robust design includes galvanic isolation between the input, output, programming output, and power supply, enhancing the safety and integrity of your signal processing. The unit's functionality is further enhanced by its programmable fault signal response, with a red flashing LED providing clear indication of any errors per NAMUR NE 44 recommendations.
Ideal for process automation applications, the Pepperl + Fuchs KFD2-UT-EX1 is a reliable and precise solution for temperature signal conversion in potentially explosive environments. Its compact and user-friendly design makes it a valuable addition to any industrial temperature monitoring and control system.
