Purchasing genuine Pepperl+Fuchs safety barriers, inventory reserves and supply, good services are available at okplazas.com

P+F safety barriers are usually installed in the control room. Pepperl+Fuchs safety barriers have two types: isolation barriers and Zener barriers. Sparks can be avoided by limiting the energy entering the site to achieve explosion-proof effects. Provide an intrinsically safe circuit for field instruments, and achieve the goal of not generating sparks or temperature rise by limiting the pressure, so as to achieve explosion-proof.

Pepperl+Fuchs Safety Barrier

When using safety barriers, to ensure that the safety barrier system works normally, it is necessary to determine the parameters of the safety barrier according to the system parameters. The Zener safety barrier mainly depends on the working voltage, the highest working voltage, the terminal resistance parameters, etc., which are widely applicable Petrochemical, coal, oil refining, explosion-proof and flammable occasions. The use of safety barriers is compatible with the requirements of intrinsic safety instrumentation and the impedance matching problem in the intrinsically safe system is formed. The special industrial site Pepperl+Fuchs safety barrier requires two-wire transmission, which not only provides power distribution and signal isolation, but also needs to have the performance of safe spark-proof explosion-proof, which can reliably prevent the mixed contact between the high voltage of the power supply and the signal, and use the current , Voltage double limit circuit, limit the energy entering the dangerous place below the safety rating. P+F series products and P+F Pepperl+Fuchs power supplies and encoders can be said to be familiar in the industrial control industry, and they are also essential products for many industrial control enthusiasts.
