P+F Pepperl+Fuchs Safety Barrier Takes you into the industrial excellent era

The P+F Pepperl+Fuchs safety barrier is mainly used for on-site explosion-proof, such as the petroleum, chemical, metallurgical and other industries that exist to a certain degree of danger. The safety barrier can be equipped with a good protection for the production site. For example, in the power distribution room of the metallurgical industry, the detection end of the power distribution isolation safety barrier is supplied from the safe area to the field transmitter in the dangerous area, providing independent isolated power for each transmitter, and the power input and output are isolated from each other.

The core components of the P+F Zener safety barrier are Zener diodes, current limiting resistors and fast fuse wires. 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. The 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 instrument connection in the explosion-proof occasions of the metallurgical industry forms an intrinsically safe circuit through the safety barrier and the intrinsically safe instrument, which plays the role of intrinsically safe explosion-proof.
