Go to okplazas.com to buy the original authentic Pepperl+Fuchs safety barrier, worry-free and trustworthy

The safety barrier is now one of the indispensable safety accessories in the industrial control industry. Related equipment of intrinsically safe explosion-proof instrumentation. It does not affect the function of the measurement system under normal conditions. The P+F Pepperl+Fuchs safety barrier is installed in a safe place. When the intrinsically safe explosion-proof system fails, it can limit the energy (electricity) entering the dangerous place within a safe value, thereby ensuring the safety of on-site production.

Pepperl+Fuchs Safety Barrier

The core components of the P+F safety barrier Zener safety barrier are Zener diode, current limiting resistor and fast fuse. The isolated safety barrier not only has a limited energy function, but also an isolation function. It is mainly composed of a loop energy limited unit, a signal and power isolation unit, and a signal processing unit. Pepperl+Fuchs isolation barrier can output two mutually isolated signals to provide to two devices using the same signal source, and ensure that the signals of the two devices do not interfere with each other, and at the same time improve the electrical safety insulation performance of the connected devices. The second is that because the signal lines do not need to share the ground, the stability and anti-interference ability of the detection and control loop signals are greatly enhanced, thereby improving the reliability of the entire system. The third is that due to the three-way isolation method, there is no need for system grounding, which brings great convenience to design and on-site construction. The P+F Pepperl+Fuchs safety barrier provides an intrinsically safe circuit for field instruments. By limiting the voltage limit, it can achieve the purpose of not generating electric sparks or temperature rise, so as to achieve explosion-proof. In addition to safety barriers, okplazas.com also supplies P+F encoders, P+F sensors, P+F power supplies, P+F surge protectors and other brand products for a long time.
