An intrinsic safety barrier is used to provide protection to a device mounted in a hazardous location.


Isolated barrier is used in intrinsic safety explosion-proof industry process control system, ensuring safety of intrinsic safety equipment, which are key electronic interfaces of preventing explosion via limiting power  along with function like transmittor/distribution/signal matching/anti-interference in signal transmission between dangerous areas and safety areas.


The basic components that make up most intrinsic safety barriers are a fuse, zener diodes, and a resistor and are shown below in this simple electrical diagram:


           Why use an intrinsiaclly safety isolated barrier


 An isolated barrier is a component installed in a safe area. Its circuit structure, including an IS circuit and a non-IS circuit, prevents non-IS circuits from adversely affecting IS circuits. The primary concept behind intrinsic safety is the restriction of available electrical and thermal energy in the system so that ignition of a hazardous atmosphere (explosive gas or dust) cannot occur. This is achieved by ensuring that only low voltages and currents enter the hazardous area, and that no significant energy storage is possible.
