okplazas.com Pepperl+Fuchs Safety Barrier Friendly Reminder Pay attention to production safety at high temperature

The application of safety barriers in the petrochemical industry is almost ubiquitous, providing a good guarantee for production safety and the stable development of economic output. There are two types of safety barriers: Zener barrier and isolation barrier. Today we share with you the application guidelines of Pepperl+Fuchs safety barrier isolation barrier.

Pepperl+Fuchs Safety Barrier

It is strictly forbidden to use a megohmmeter to test the insulation between the terminals of the isolation barrier during use of the P+F isolation barrier. 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. MTL isolation safety barriers should be installed in non-hazardous locations. The cross-sectional area of ​​the soft copper wire leading from the isolated safety barrier to the site (dangerous place) must be greater than 0.5mm2. The insulation strength of the connecting wire is greater than 500V. The intrinsically safe end (marked in blue) and the non-intrinsically safe end circuit wiring of Pepperl+Fuchs isolated safety barrier shall not be connected wrongly or mixed up. Intrinsically safe conductors should use blue as the intrinsically safe mark. Intrinsically safe conductors and non-intrinsically safe conductors should be laid separately in the junction duct, using their own protective sleeves. On the intrinsically safe side of the MTL isolated safety barrier, it is not allowed to confuse other power sources, including the power sources of other intrinsically safe circuits. okplazas.com supplies P+F Pepperl+Fuchs safety barriers from stock, signed a contract to guarantee the original authenticity, and the product is guaranteed for one year.
