Product Description
Pepperl+Fuchs KFU8-UFC-1.D Frequency Converter
This 1-channel universal frequency converter and signal conditioner converts digital frequency input signals into proportional analog output signals (0/4-20 mA) while functioning as a switch amplifier and trip alarm device.
Product Overview
The Pepperl+Fuchs KFU8-UFC-1.D accepts inputs from NAMUR sensors (acc. to EN 60947-5-6), 2/3-wire sensors, or dry contacts, with frequency measurement from 0.001 Hz to 12 kHz. It features four independent outputs (2 relay + 1 transistor + 1 analog) for exceptional flexibility in industrial automation and process control applications.
Note: A successor product is available. Please verify stock availability before ordering.
