The safety barrier is also known as the safety keeper, the safety interface of the intrinsically safe circuit. It can transmit electrical signals in both directions between the safe zone and the dangerous zone, and can limit the transfer of the safe zone to the dangerous zone and energy caused by faults. Pepperl+Fuchs safety barriers are available in two types: Zener type and isolated type. Flexible use in different industrial control occasions.

Pepperl+Fuchs Safety Barrier

The Pepperl+Fuchs safety barrier is equipped with warning lights or other obvious signs. If the isolation barrier is made of metal, it must be safely and reliably grounded. The safety barrier is used to limit the electrical energy supplied to the field instruments from the control room to the point that it can neither generate enough sparks to detonate dangerous gases, nor produce enough instrument surface temperature to detonate dangerous gases, thereby eliminating the source of detonation. When selecting a safety barrier, it must be considered that its model is compatible with the type of field instrument, and the compatibility of the safety barrier with the requirements of intrinsic safety instruments and the impedance matching in the intrinsically safe system formed must also be considered. In practice, this method has many restrictions on the selection of safety barriers and field equipment. The isolation barrier is the best explosion-proof product that is most suitable for installation on operating equipment, relays and other equipment. The Pepperl+Fuchs safety barrier can limit the energy entering the dangerous place within a safe value when the intrinsically safe explosion-proof system fails, thereby ensuring the safety of on-site production.
