1. Summary
     Pors-GN passive signal isolators are used without external power suply, its power to work comes from input current. In actual application, it can solve problem caused by signal connection and suppress interference in signal transmission effectively. 
     Power, input, output are isolated from each other, two channels are isolated and independent.
     Input loop and output loop is isolated.

2. Technical index
