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.
Pepperl+Fuchs offers a variety of intrinsic safety barriers for different requirements. Select between isolated barriers and Zener barriers that ensure safe signal transmission in hazardous areas.
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.
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.
It interrogates each HART device, retrieves device information, and stores it in an internal database. This information is made available by the AMS Device Manager or PACTware. The HART Multiplexer also acts as a message coordinator for communication between the maintenance workstation PC and the HART devices. For a single loop solution, the HART Loop Converter allows access to all process variables provided by a field device and transfers them to conventional 4…20 mA loop. This enables it to make use of the hidden measurements done by many field devices and feed them to conventional DCS Systems.
In process engineering plants such as refineries with exposed building parts or extensive water management systems, surge eventscan cause disastrous consequences: from damage or destruction of expensive components and machines to breakdown of complete automation systems—not including risks to personnel.
Besides these dangerous risks to people and environment, overvoltages are still one of the most common causes of damage in electrical plant engineering. They primarily occur due to lightning strikes or switching operations, but also due to the following causes:
- Electrostatic discharge
- Brush fire of large electric machines
- Fluctuations in power supply
- Ground faults / short circuits
- Triggering fuses
- Parallel installation of energy and information technology control systems
Pepperl+Fuchs‘ surge protection modules reliably divert surges and currents to ground and protect people and machines against possible negative consequences. Our product range provides you with powerful surge protection solutions for various applications. Find devices for signal line protection, supply line protection, fieldbus, and wireless solutions.
