Product Description
Pepperl+Fuchs KFU8-UFC-Ex1.D Frequency Converter
1-Channel Isolated Barrier with 0.001-5000Hz Input, 4-20mA Output, SIL2 Certified
Product Overview
The Pepperl+Fuchs KFU8-UFC-Ex1.D is a 1-channel isolated barrier frequency converter from the K-System, designed for intrinsic safety applications in hazardous areas. This versatile device converts digital input frequency signals into proportional 0/4-20 mA analog output signals while functioning as both a switch amplifier and trip alarm.
Note: A successor product is available. Please verify stock availability before ordering.
