The Pepperl+Fuchs KFD2-STC5-1 is a 1-channel signal conditioner from the company's K-System family of isolated barriers and signal converters, specifically for industrial process automation environments where reliable power delivery, signal integrity, and galvanic isolation are paramount. This module serves as the critical interface between SMART field transmitters located in the process area and control system I/O cards in the safe area, ensuring that analog measurement signals and superimposed digital communication are transferred accurately, safely, and without electrical interference.

The KFD2-STC5-1 Pepperl+Fuchs SMART Transmitter Power Supply may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Pepperl+Fuchs KFD2-STC5-1 SMART Transmitter Power Supply Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
At its core, the KFD2-STC5-1 is a SMART Transmitter Power Supply that energizes and communicates with 2-wire and 3-wire SMART transmitters as well as 2-wire SMART current sources. It accepts a standard 4–20 mA analog input signal from the field device and reproduces it as an isolated 4–20 mA output on the control side. The module's power supply input accepts 18–30 V DC (nominal 24 V DC) with ripple tolerance within the supply range, and can be connected via conventional screw terminals (14+, 15–) or through the Power Rail system—a busbar solution that daisy-chains power across multiple K-System modules, significantly reducing wiring complexity in large installations. Maximum power consumption is ≤1.6 W and power dissipation is ≤1 W at full load, ensuring minimal thermal impact on densely packed control cabinets.
