Safety Barrier

Safety Barrier must be installed in the security zone, connects the primary instruments in the dangerous zone and the secondary instructions in the safety zone. When the input voltage and output current are normal circumstances, Safety Barrier does not affect the accuracy of the primary equipments. Once the power supply voltage or output current is bigger than the threshold of the Safety Barrier, Safety Barrier will enter the limiting state.
