When introducing electrical equipment into a hazardous area, extensive regulations need to be observed to maintain maximum safety in any circuit. That's why Pepperl & Fuchs design and supply the markets largest range of hazardous area equipment.

Isolated barriers

Intrinsic safety barriers are the core of Pepperl+Fuchs' product portfolio. We offer the widest selection of products for protection of electrical signals located in hazardous areas. These intrinsic safety modules combine the energy limiting features of a zener barrier with  galvanic isolation. Pepperl+Fuchs offers systems for different applications and mountings.

Zener Barriers

Zener barriers provide cost saving Ex-protection for various applications in process automation systems. The amount of energy transferred to the hazardous location is limited to a safe level incapable of igniting the explosive atmosphere. Pepperl+Fuchs offers a wide product portfolio of housing and connection styles, which include DIN rail, termination board mounted, and accessories for each application.

Signal Conditioners

With the variety of process control systems available, it is often necessary to convert an input signal into a format that the system will accept. Signal conditioners take signals from an assortment of field instruments such as replicas relojes thermocouples and RTDs, and convert those signals into any of several standard instrument signals (1…5V, 4…20 mA, etc.).

Signal conditioners are also beneficial to the accurate transfer of these signals, isolation and the elimination of ground loops.
