Im K-System from Pepperl+Fuchs, safety is the top priority: The isolation barrier limits the energy fed into the intrinsically safe circuit, while the galvanic isolation protects measurement and control circuits from interference such as ground loops, thus ensuring high signal reliability. The system is G3-compliant and supports safety requirements up to SIL 3 for all signal types.
Wide selection of cost and space-saving modules
With 200 isolation barriers and 150 signal isolators, the K-System is the largest product portfolio of its kind. The possible applications are virtually unlimited, both in hazardous areas and in mixed hazardous and non-hazardous areas. The product family consists of a wide range of modules - from simple switch amplifiers to highly functional components, including modules for all signal types and customizable multifunctional devices for every application.
Easy installation and maintenance are ensured by removable terminal blocks with test sockets and the internal diagnostic function of the modules. The Hart signal transparency enables easy access to the field devices. In addition, the K-System modules can reduce costs and save space in the control systemcabinet can be saved because they have a packing density of up to 6 mm per channel and have a long service life due to low power consumption and low heat dissipation.
AI/AO barrier controls and monitors valve positioner
As the first 2-channel AI/AO barrier for intrinsically safe applications, the KCD2-SCS* module a flexible configuration for analog input or output signals. Thanks to its slim 12,5 mmhousing and a high packing density of 6 mm per channel, the module can be installed in control technology in a space-saving mannerSchränke The Hart-compatible interface modules are suitable both as smartTransmitterpower supplies for 2-wire transmitters as well as smart output drivers for valve position controllers, enabling versatile and efficient use.
Profile rail saves space in the housing
The profile rails of the K-Duct Series offer a clever solution where the cable channels behind the DIN rail. Thanks to an integrated partition, input and output wiring are cleanly separated. This creates a safe distance between potentially explosive and non-potentially explosive signals. Since the cabling Since no additional space is required above the DIN rail, the available space is used efficiently. Compared to conventional systems, K-Duct enables a 50% higher packing density per housing.
Global service with high availability
The K-System provides line fault monitoring for field circuits and modules, which provides line fault transparency and maximum availability The modules can be mounted both horizontally and vertically without affecting the operating values. Minimized downtimes are guaranteed by replacing the modules during operation. The operating temperature range is between -40 °C and +70 °C.
Pepperl+Fuchs offers 80 branches local support worldwide and ensures international and local approvals for the global use of the K-System. With over 70 years of experience in signal processing in potentially explosive areas, the company offers an unparalleled level of expertise.
Frequently asked questions
What is an Ex protection area?
An explosion-proof area is an area in which explosive atmospheres can occur due to gases, vapors or dust. Special safety regulations apply here to avoid sources of ignition and prevent explosions. Equipment and installations must meet the requirements of explosion protection (Ex protection) as specified in standards such as Atex and Iecex.
What is an ATEX zone?
An Atex zone defines Areas in which explosive atmospheres can arise due to gases, vapors or dust. These zones are divided into categories that describe the risk and frequency of the occurrence of explosive mixtures. Equipment in these areas must comply with the Atex directives to avoid sources of ignition and ensure safety.
Which Ex zones are there?
There are three Ex zones for gases and vapors:
- 0 Zone: Permanent or long-term presence of explosive atmosphere
- 1 Zone: Occasional presence of explosive atmosphere
- 2 Zone: Rare or short-term presence of explosive atmosphere
There are also three zones for dust:
- 20 Zone: Permanent or prolonged presence of explosive dust
- 21 Zone: Occasional presence of explosive dust
- 22 Zone: Rare or short-term presence of explosive dust
The correct classification ensures the safety of equipment and systems in potentially explosive areas.
