Pepperl+Fuchs SMART Transmitter Power Supply KCD2-STC-EX1
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-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.
Selectable output of current source, sink mode, or voltage output is available via DIP switches.
If the HART communication resistance in the loop is too low, the internal resistance of 250 Ω between terminals 6 and 8 can be used.
Test sockets for the connection of HART communicators are integrated into the terminals of the device.
