Pepperl+Fuchs isolated barrier KFD2-STC4-Ex1-Y1

SMART Transmitter Power Supply, Output Current Sink KFD2-STC4-Ex1-Y1

Pepperl+Fuchs isolated barrier KFD2-STC4-Ex1-Y1

Features
• 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 current sink
• Terminal blocks with test sockets
• Up to SIL 2 acc. to IEC 61508


Function
This isolated barrier KFD2-STC4-Ex1-Y1 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. Pepperl+Fuchs isolated barrier KFD2-STC4-Ex1-Y1
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. It is designed to provide a sink mode output on the safe area terminals. Pepperl+Fuchs isolated barrier KFD2-STC4-Ex1-Y1
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.

Application
The device supports the following SMART protocols:
• HART
• BRAIN
• Foxboro
