Function 

Pepperl+Fuchs SMART Transmitter Power Supply 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. Pepperl+Fuchs SMART Transmitter Power Supply KFD2-STC4-Ex1

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.

Application 

Pepperl+Fuchs SMART Transmitter Power Supply KFD2-STC4-Ex1

The device supports the following SMART protocols: 

• HART 

• BRAIN 

• Foxboro
