okplazas.com original authentic Pepperl+Fuchs safety barrier, quality assurance and reliable reputation

Pepperl+fuchs safety barriers are now more practical and widely used in the industrial control industry, which provides a good guarantee for the explosion-proof safety of industrial sites and the arrangement of operators. Pepperl+Fuchs safety barriers provide intrinsically safe circuits for field instruments, which can achieve the purpose of not generating sparks or temperature rise by limiting the pressure, so as to achieve explosion-proof.

Pepperl+Fuchs Safety Barrier

The safety barrier is also called the safety retainer. The safety interface of the intrinsically safe circuit can transmit electrical signals in both directions between the safe area and the dangerous area, and can limit the safe area to the dangerous area and energy transfer caused by the fault. Pepperl+Fuchs safety barriers are available in two types: Zener type and isolated type. It mainly serves the instrument, usually installed in the control cabinet together with the control system. The industrial control application of Pepperl+Fuchs safety barrier directly affects the economic growth of the economy and better maintains the safety of production. An energy-limiting interface between field equipment and control room equipment. Therefore, regardless of whether the control room equipment is in a normal or faulty state, the safety barrier can ensure that the energy transmitted to the field equipment through it is intrinsically safe. Reliably prevent the mixed contact between the high voltage of the power supply and the signal, and use the current and voltage double limit circuit to limit the energy entering the dangerous place below the safe rating. Pepperl+Fuchs safety barriers are widely used in the fields of chemical and petrochemical, water treatment, metallurgy, pharmaceuticals, electric power, cement, pulp and paper making, and utility automation.
