Intrinsic Safety Barriers

Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres. This simplifies maintenance and repair of Ex i circuits

FieldConnex Fieldbus Infrastructure

FOUNDATION fieldbus H1 and PROFIBUS PA link field instrumentation to any process plant. Fieldbus provides seamless data communication between the plant and control system while supplying power to all field devices.

Fieldbus topologies fit the demands of modern process industries. The High-Power Trunk approach provides plenty of energy and the flexibility you expect for your process. Make the High-Power Trunk your choice of fieldbus technology for FOUNDATION fieldbus H1 and PROFIBUS PA

HART Interface Solutions

HART Interface Solutions from Pepperl+Fuchs consist of two HART Multiplexer Systems for multiple signal loops and a HART Loop Converter for single loop applications. The Multiplexer is used to connect HART field devices to Asset Management Systems like AMS™ Suite: Intelligent Device Manager from Emerson Process Management. At the heart of HART Interface Solution (HIS), the HART Multiplexer acts like a gateway device, routing communications between the maintenance workstation PC and the HART field devices.

Signal Conditioners

Signal conditioners protect signal transfer between field devices in safe areas and control systems by galvanic isolation of the loop.

Particularly in case of long transmission paths, signal conditioners avoid compensating currents which may occur from ground loops. Signal conditioners also offer effective protection against electromagnetic disturbance or dangerous over voltages on the signal loops.

Depending on the type, signal conditioners offer additional features like limit switching, transformation from field in standard signals, as well as splitting of signals, which means doubling the input signal

Remote I/O Systems

Modular remote I/O systems transmit process data from safe or explosion hazardous areas by connecting binary and analog sensors and actors to the control system via a bus interface. Remote I/O is the right choice when you want to put I/O modules close to the field devices. Due to the reduced wiring effort, you not only save cables, but also time, money, and work effort. Hence, remote I/O field units can be installed in a decentralized location inside hazardous areas while you easily control and monitor sensors and actors from the control room.

Surge Protection

In process engineering plants such as refineries with exposed building parts or extensive water management systems, surge events can cause disastrous consequences: from damage or destruction of expensive components and machines to breakdown of complete automation systems—not including risks to personnel.

Wireless Solutions

Wireless communication quickly gains relevance in automation applications. For process automation, it is not the amount of data that poses challenges, but the distances to be bridged. Whenever the plant architecture does not allow conventional wiring, values are only accessible through frequent visits to the field.

Purge and Pressurization Systems

Pepperl+Fuchs offers a full range of purge and pressurization equipment to meet the needs of your application. Another benefit of purging and pressurization is use of the standard Type 4/12 enclosure as the protected enclosure. This saves money, weight, and space over explosion-proof methods. Need a certified solution? The Pepperl+Fuchs Systems and Solutions group can also design custom, certified enclosure solutions.

Electrical Explosion Protection Equipment

Pepperl+Fuchs offers a broad portfolio of electrical equipment and solutions for installation and control of machinery and electrical networks in harsh environments and explosion hazardous areas.

Various types of protection and enclosure variants along with a high level of flexibility allow the design of the most efficient control and distribution solutions for any application and industrial environment.



Pepperl+Fuchs understands the need for reliable power in hazardous areas. Our power supplies meet the most demanding requirements for today's process control applications, and help to enhance system integrity. Our power supplies are well suited for emergency shut down and mission critical applications to fieldbus and analog networks including HART communication.

Level Measurement

Today, level measurement technology is the basis for management and process control in the chemical, petrochemical, environmental and other related industries.
Our comprehensive program enables us to help you solve your particular measurement and control problems and to detect the precise level of any medium, under a wide range of conditions.
