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.

K-System
Our most popular intrinsic safety isolated barriers are the flexible DIN rail mounted K-System modules. The K-System intrinsic safety barriers connect easily with our Power Rail assembled in the DIN rail. The use of the Power Rail reduces the wiring by energizing the modules mounted on the DIN rail.

WE-System
The WE-System isolated switch amplifiers provide power to NAMUR proximity sensors or dry contacts located in hazardous environments. The units can be installed onto a DIN-Rail or by mounting them with screws through holes in the base. For new installations we recommend to use our K-System isolated barriers.

K-System
K-System interface technology
Solving a wide range of applications in one system, our K-System guarantees a reliable and economical signal transmission between your field device and the control system. Whether your plans include a single isolating module or a large scale system integration, application-oriented solutions characterize the entire K-System product range.

Product portfolio
K-System offers an extensive range of intrinsic safety interface modules for many signals and applications - from simple isolators to highly functional modules.

Power Rail
The Power Rail is an insert in the standard 35mm DIN rail. When mounting on the DIN rail, the units are simply snapped in place. The Power Rail supplies the modules with power and provides a path for the collective error message from individual isolators. Power Rail reduces wiring and maintenance costs because it eliminates the need to daisy chain the wires. It also simplifies expansion. Just snap in a new module when you're ready to add to your system.

International safety standards
SIL ratings are available at no extra charge.

Easy configuration
With our powerful software tool, PACTware, Project documentation is easier to create and highly functional interface modules are easily configured.

The Industrial Safety Systems and Their Types Industrial automation has minimized the human interaction with the machines but has not completely eliminated it. Industrial safety systems are introduced to protect the human who work in hazardous plants. Some examples of these are oil and gas, chemical and nuclear plants. The industrial safety systems not only protect the humans but also protect the environment and the plant itself from the chemical reactions. These systems do not control any process but in fact come into play when it is not possible to control a process through normal means. They are rather installed as a protective measure and are quickly becoming the need of every working environment. There are various types of safety systems in place and their use depends on the type of industry they are used in. Here is a look at some of them. Process Control Systems (PCS) They are installed for the monitoring of the manufacturing environment and they control the manufact

PROFIBUS

 PROFIBUS PROFIBUS or Process Field Bus was introduced in 1989 and it is sometimes confused with PROFINET. It links plant automation modules with the process control. PROFIBUS uses a multi drop single cable to connect the devices. This method is cost effective especially for larger sites when compared to old methods. Its installation cost is low and it is easy to find faults as well because it is a single cable. Types of PROFIBUS There are two types or versions of PROFIBUS commonly known as 1.    PROFIBUS DP 2.    PROFIBUS PA Here is a brief introduction to both of these types. PROFIBUS DP It runs over two core screened cable that is violet sheathed and its speed varies from 9.6Kbps to 12Mbps. A particular speed can be chosen for a network to give enough time for communication with all the devices present in the network. If systems change slowly then lower communication speed is suitable and if the systems change quickly then effective communication will happen through

Analog Input/Output Modules

Analog Input/Output Modules Analog Input Modules To select an analog input module the consider the followings: *Voltage level. *Current input. *Conversion speed. There are two basic types of A/D converter. The first will perform a conversion every 20 ms (the period of the a.c. mains voltage), which gives a good clean reading free from worries of line frequency interference. The second will convert in 2-20 us, giving the possibility of measuring transient data. *At very high rates the PLC may only have time to act as a data logger, storing the data as it is read, and analyzing it some time after the event to report on or display it. Analog Output Modules *The conversion speed of an analog output is generally <100 us and rarely a problem. * Once the resolution of the module is selected we have only to consider the following points: Voltage level. Load resistance. Typically the minimum load resistance is 300 Ohm. Current output. It is often a
