okplazas.com original authentic Pepperl+Fuchs safety barrier service is not only the brand

Pepperl+Fuchs safety barriers have two types: Zener barriers and isolation barriers. The most commonly used is Pepperl+Fuchs isolation barriers. Pepperl+Fuchs isolation barrier can effectively isolate the field loop signal in the hazardous area from the loop signal in the safe area. The intrinsically safe automatic control system does not require an intrinsically safe grounding system, which simplifies the construction of the intrinsically safe explosion-proof system.

Pepperl+Fuchs Safety Barrier

The P+F safety barrier isolation barrier greatly enhances the anti-interference ability of the detection and control loop, and improves the system reliability. Use isolation barriers, allow field instruments to be grounded, and allow field instruments to be non-isolated. The isolated safety barrier has many protective function circuits, and the possibility of accidental damage is small. On-site instrumentation is allowed to be overhauled with power, which can shorten the preparation time of the project and reduce the parking time. The Pepperl+Fuchs safety barrier uses fast fuses, current-limiting resistors or voltage-limiting diodes to limit the input electrical energy, so as to ensure the energy output to the hazardous area. Pepperl+Fuchs safety barriers have simple principles, easy circuit implementations, and low prices. However, due to their own principle defects, their reliability in application is greatly affected. The P+F isolated safety barrier has strong signal processing capabilities. The loop-powered isolated P+F safety barrier not only maintains the advantages of an active isolated safety barrier, but also has the same wiring convenience as a Zener safety barrier. It does not require another 24V power supply. It is especially suitable for DCS with I/O card direct power supply. system.
