The Pepperl + Fuchs KFD2-STC5-1 provides essential galvanic isolation for industrial sensor networks. This device supplies power to 2-wire and 3-wire SMART transmitters in the field. It also supports 2-wire SMART current sources. By separating field circuits from control side terminals, the module eliminates ground loops and protects the control system from electrical surges. The unit converts analog input signals into isolated 4-20 mA current values, ensuring high-precision data transmission across the isolation barrier.
Advanced HART Communication and Integration
Maintenance teams benefit from the bidirectional digital communication features of this module. It allows HART, BRAIN, or Foxboro protocols to pass through the signal without interference. Specifically, the KFD2-STC5-1 includes an internal 250 Ohm resistor for HART compatibility. Integrated test sockets allow for direct communicator connection, which streamlines field calibration and system troubleshooting. Furthermore, the output stage offers flexibility by operating in either sink or source mode to match diverse PLC and DCS input requirements.
