Pepperl+Fuchs KFD2-STC5-1 SMART Transmitter Power Supply

The Pepperl+Fuchs KFD2-STC5-1 SMART is a smart power isolator designed specifically for industrial transmitters. It combines power and signal isolation, serving as a "safe power manager" for field instruments. It delivers stable 24V DC power to the transmitter while electrically isolating and filtering the 4-20mA analog signal it returns, accurately transmitting it to higher-level systems such as PLCs and DCSs.
This device features a compact design and a rugged housing, ensuring stable power supply and pure signal transmission even in industrial environments subject to electromagnetic interference and complex grounding, such as those in the chemical, petroleum, and metallurgical industries. Its two-in-one "power + isolation" feature eliminates the need for separate power supplies and isolators, saving control cabinet space and simplifying system wiring. It is a key component for enhancing safety and reliability in industrial automation signal chains.

• This signal conditioner provides the galvanic isolation between field circuits and control circuits.
• The device supplies 2-wire and 3-wire SMART transmitters, and can also be used with 2-wire SMART current sources.
• It transfers the analog input signal as an isolated current value.
• Digital signals may be superimposed on the input signal on the field side or on the control side and are transferred bidirectionally.
• The device provides a sink mode or a source mode output on the control side terminals.
• The device has an internal resistor. Use this resistor if the HART communication resistance in the control circuit is too low.
• Test sockets for the connection of HART communicators are integrated into the terminals of the device.
