KAG-5□□□ isolated safety barrier is a type of cassette-series instrument. In normal state, safety barrier does not affect the normal operation of the system. When it is fault, the safety barrier will limit voltage and current and restrict electric energy within limits to ensure safety. It is widely used in petroleum, chemical industry, light industry and other inflammable and explosive places. It has the following characteristics:

Detected terminal barrier is used with two-wire transmitter and supply power for it. It can restrict dangerous energy enter into dangerous place. Isolated safety barrier can convert 4～20mADC signal from transmitter to isolated 4～20mADC signal output.

To compare with zener safety barrier, isolated safety barrier can isolate signal. Cassette-type can be installed on DIN rails to save the control cabinet space.
