Safety is put first with the use of the K-System from Pepperl+Fuchs: Its barrier function limits the energy fed into the intrinsically safe circuit. The galvanic isolation of the measuring and control circuits protects control systems and field devices from interference caused by ground loops, ensuring signal reliability. The K-System is G3 compliant and enables up to SIL 3 to be achieved for all signal types.
Wide Choice of Cost- and Space-Saving Modules
With 200 isolated barriers and 150 signal conditioners, the K-System is the largest product portfolio of its kind. The possible applications are practically unlimited, both in hazardous areas and in mixed Ex and non-Ex 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 any application.
Simple installation and maintenance are ensured by removable terminal blocks with test sockets and the internal diagnostic function of the modules. HART signal transparency allows easy access to the field devices. In addition, K-System modules help reduce costs and save space in the control cabinet with their packing density of up to 6 mm per channel as well as their long service life due to low power consumption and low heat dissipation.
High Availability and Global Service
For maximum availability, the K-System features line fault detection of field circuits and modules with line fault transparency. The modules can be mounted horizontally and vertically without de-rating the operating values. Downtime is minimized as the modules can be hot swapped during operation. The operating temperature range extends from -40 °C to +70 °C.
If service is needed, 80 offices worldwide offer dedicated local support. International and local approvals are also available for the implementation of K-System products anywhere in the world.
Valve Positioner Control and Monitoring with Only One Device
As the first 2-channel AI/AO intrinsic safety barrier with dual function, the KCD2-SCS* can be configured individually for analog input or analog output control signals. With a compact 12.5 mm housing and a packing density of 6 mm/channel, the new module enables space-saving integration into the control cabinet. The interface modules are HART-compatible and can be used both as SMART transmitter power supplies for two-wire transmitters and as SMART current drivers for valve positioners.
