The explosion-proof principle of P+F multiplier Zener grid is to use a Zener diode to control the output voltage and a resistor to limit the output current. The circuit is relatively simple. When the production industry is working normally, the Zener safety barrier is equivalent to two resistors in series into the circuit, so there is no need to change the system structure.

P+F Pepperl+Fuchs isolation barrier is strictly prohibited to use a megohmmeter to test the insulation between the terminals of the isolation barrier during use. If you want to check the insulation of the system circuit, you should disconnect all the isolated safety barrier wiring, otherwise it will cause damage to the internal components. Therefore, when the isolated safety barrier is individually energized and debugged, you must pay attention to the type and power pole of the isolated safety barrier. Characteristic, voltage level and the label on the terminal of the isolated safety barrier shell. Isolated safety barriers should be installed in non-hazardous locations. The basic principle of intrinsic safety is very simple. All flammable materials are grouped according to the amount of energy required to ignite them. All intrinsically safe equipment is designed and certified to be safe for a certain gas group. In many industrial processes, some flammable materials need to be handled, and any leakage or splashing can create an explosive environment. Make sure that this environment will not be ignited. The difference between intrinsic safety and explosion-proof is that the intrinsic safety of the equipment material and circuit is required, 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.
