PRODUCT DESCRIPTION
PEPPERL & FUCHS KFD2-CD-EX1.32 (Order No. 109176) - Intrinsic Safety Barrier, Current Driver
This K-System KFD2 series intrinsic safety barrier provides galvanic isolation and signal conditioning for 2-wire transmitters located in hazardous areas. It converts the intrinsically safe input signal into a safe-area 4-20mA current output, facilitating seamless integration with control systems while supporting HART communication pass-through. Engineered for critical process automation applications requiring SIL 2 functional safety.
