Pepperl+Fuchs KFD2‑UFC‑Ex1.D | Universal Frequency Converter | Intrinsically Safe | DIN-Rail Signal Conditioner
Overview
The Pepperl+Fuchs KFD2‑UFC‑Ex1.D is a compact, intrinsically safe frequency-to-current converter. It takes pulse/frequency signals from hazardous (Ex) areas and converts them into a reliable 4–20 mA analog output, isolating and safeguarding the control system. Designed for seamless DIN-rail integration, it's ideal for industrial signal processing where safety is critical.
Key Features
-
Accepts pulse or frequency inputs from Ex-rated pulse sources
-
Outputs isolated 4–20 mA current signal
-
Intrinsically safe input certified for hazardous zones (Ex‑ia)
-
Passive, loop-powered design—no external power needed
-
LED indicators for status and fault diagnostics
-
Compact 12.5 mm DIN-rail housing
-
Designed for integration in hazardous-area signal racks
