Intrinsically safe explosion-proof expert Pepperl+Fuchs safety barrier okplazas.com Hot spot

The difference between P+F Pepperl+Fuchs safety barrier's intrinsic safety and explosion-proof is that it requires the intrinsic safety of the equipment material and circuit, and the explosion-proof is through the shell and additives. Intrinsically safe type is intrinsically safe, and explosion-proof type is required for explosion-proof performance. The installation of the safety barrier needs to pay attention to some defensive measures, such as the need to connect the ground wire. During the installation process, there is a very reliable grounding system that requires the isolation type required by the field instruments from the hazardous area.

Modern industry must pay attention to the type of isolated safety barrier, power polarity, voltage level and the label on the terminal of the isolated safety barrier when conducting separate power-on debugging for isolated safety barriers. The surge protector equipped with the isolation barrier is for overvoltage protection, such as lightning strikes, operating overvoltages, etc., through surge absorbers to limit the voltage range and protect the equipment. The isolation barrier limits the energy on the circuit, making it lower than the energy for igniting explosive dangerous objects to prevent explosion. The function of the surge protector is to protect the main switch from high current, the surge protector will play a role in discharging to the ground. It is to prevent the main switch from malfunctioning and cause unnecessary power outages. The P+F Pepperl+Fuchs safety barrier is connected between the essential full circuit and the non-intrinsically safe circuit. A device that limits the voltage or current supplied to an intrinsically safe circuit within a certain safety range.
