Description Pepperl Fuchs KFD2-UFC-Ex1.D Frequency Converter with Trip Values The Pepperl Fuchs KFD2-UFC-Ex1.D is a sophisticated 1-channel isolated barrier designed for intrinsic safety applications in demanding hazardous environments. This universal frequency converter is critical for process automation, as it transforms digital input signals into a proportionally adjustable 0/4 mA to 20 mA analog output signal, while simultaneously serving as a switch amplifier and trip alarm. It ensures safe signal transmission between field devices located in Zone 0/Div. 1 and control systems in the safe area. Engineered for high-precision field performance, the KFD2-UFC-Ex1.D handles a broad input frequency range from 1 mHz to 5 kHz. It offers versatile configuration options through a dedicated keypad, LC display, or PACTware software, allowing for easy adjustment of trip values (min/max alarms), pulse dividers, and error signal outputs. The device features a start-up override function and comprehensive line fault detection (LFD) to maintain operational uptime and safety integrity.
