This isolated barrier is used for intrinsic safety applications. It is loop-powered and repeats a 4 mA ... 20 mA signal from a current source inside a hazardous area to the safe area (It does not provide power for transmitters inside the hazardous area.). The 25.2 V, 0 mA entity parameters make it easy to design intrinsically safe systems.
