P+F Pepperl+Fuchs safety barrier guarantee without risk

P+F Pepperl+Fuchs adopts a circuit structure that electrically isolates the input, output, and power supply from each other, and meets the requirements of intrinsically safe limited energy. Compared with Zener-style security, although the price is slightly higher, its other outstanding advantages have brought greater benefits to user applications. The P+F Pepperl+Fuchs tripartite isolation method eliminates the need for system grounding, which brings great convenience to design and on-site construction.

The P+F 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 between the connected devices performance. Therefore, comparing the characteristics and performance of Zener and isolated safety barriers, it can be seen that isolated safety barriers have outstanding advantages and a wider range of uses. Although its price is slightly higher than that of Zener safety barriers, from the design, Considering the cost of construction, installation, commissioning and maintenance, the overall cost may be lower than the Zener safety barrier. Almost without exception, isolation safety barriers are used as the main intrinsically safe explosion-proof instruments in high-demand engineering sites. Isolated safety barriers have gradually replaced Zener safety barriers and have been increasingly used in the field of safety and explosion protection. There are basically two types of isolated safety barriers: detection end safety barriers and operating end safety barriers. The detection end safety barrier is used in conjunction with a two-wire transmitter; the operation end safety barrier is used in conjunction with an electrical converter or electrical valve. There are also isolated safety barriers such as signal input.
