Pepperl+Fuchs KFU8-UFC-1.D | 1-Channel Frequency to Analog Converter
Pepperl+Fuchs KFU8-UFC-1.D signal conditioner. Converts 1 mHz–12 kHz input to 0/4–20 mA, with relay outputs, SIL 2, 20–253 V AC/DC supply.
Product Overview
The Pepperl+Fuchs KFU8-UFC-1.D is a 1-channel universal frequency converter and signal conditioner designed for process and factory automation. It converts digital pulse signals (from sensors or contacts) into a proportional 0/4–20 mA analog output and provides configurable relay and transistor switching outputs. With a wide 20–90 V DC / 48–253 V AC power range and SIL 2 capability, it serves as a versatile interface for frequency monitoring, speed measurement, and trip alarm applications.
