BASIC INFO
Pepperl fuchs P+F KFD2-STC4-Ex1 Isolated barrier Transmitter Power Supply
SMART Transmitter Power Supply KFD2-STC4-Ex1
1-channel isolated barrier
24 V DC supply (Power Rail)
Input 2-wire and 3-wire SMART transmitters and 2-wire SMART current sources
Output 0/4 mA ... 20 mA
Terminals with test points
Up to SIL 2 acc. to IEC 61508
Function: KFD2-STC4-Ex1
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire and 3-wire SMART transmitters in a hazardous area, and can also be used with 2-wire SMART current sources.
It transfers the analog input signal to the safe area as an isolated current value.
Digital signals may be superimposed on the input signal in the hazardous or safe area and are transferred bi-directionally.
If the HART communication resistance in the loop is too low, the internal resistance of 250 Ω between terminals 8 and 9 can be used.
Test sockets for the connection of HART communicators are integrated into the terminals of the device.
