Product Overview
Pepperl+Fuchs KFD2-STC5-EX2 is a SMART Transmitter Power Supply and 2-channel isolated barrier for intrinsic safety applications.
This model is suitable for customers searching for Pepperl+Fuchs KFD2-STC5-EX2, KFD2-STC5-Ex2 isolated barrier, SMART transmitter power supply, HART barrier, or intrinsic safety signal conditioner quotation support.
Main Features
2-channel isolated barrier for analog input signal transmission.
24 V DC supply via Power Rail or terminals 14+ and 15-.
Input for 2-wire and 3-wire SMART transmitters and 2-wire SMART current sources.
Output signal 4 mA to 20 mA current sink or current source.
Terminals include integrated test points for HART communicators.
Functional safety up to SIL 2, systematic capability SC 3 according to IEC/EN 61508.
Function
The KFD2-STC5-EX2 supplies 2-wire and 3-wire SMART transmitters and transfers the analog input signal to the safe area as an isolated current value.
Digital signals may be superimposed on the input signal in hazardous or non-hazardous areas and are transferred bi-directionally.
The device provides sink mode or source mode output on the safe area terminals, giving flexible connection options for different control systems.
Supported Protocols
The device supports SMART communication protocols including HART, BRAIN and Foxboro.
It includes an internal resistor for cases where the HART communication resistance in the control circuit is too low.
