Description of SMART Transmitter Power Supply

This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire SMART transmitters in a hazardous area.
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.
