datasheet : KFD2-SCD-Ex1LK

The Pepperl+Fuchs  KFD2-SCD-Ex1.LK is an intrinsically safe current driver designed for hazardous areas. It serves as an interface between a control system in a safe area and a field device, such as a SMART I/P converter, electrical valve, or positioner located in a hazardous zone.

Key features:

• Intrinsically safe: Meets stringent safety standards for operation in hazardous environments where flammable gases or vapors are present.
• Current driver: Provides a stable and precise current output to power the field device.
• 1-channel isolated barrier: Isolates the control side circuitry from the field side, preventing electrical faults from propagating between the two areas.
• HART communication support: Enables communication with HART-compatible devices using digital signals superimposed on the 4-20mA analog loop current.
• Line fault detection: Detects open or short circuits in the field wiring to ensure reliable operation.
• Accuracy: Offers high accuracy of 0.1%, ensuring precise control of the field device.
• DIN rail mounting: Provides a convenient and space-saving installation method.
