PRODUCT DESCRIPTION
PEPPERL & FUCHS KFD2-STC4-EX1.2O-Y1 - 4-Channel Intrinsic Safety Barrier Signal Conditioner
This K-System module is a four-channel intrinsic safety barrier and signal conditioner designed for interfacing 2-wire and 3-wire SMART transmitters located in hazardous areas with control systems in safe areas. It provides galvanic isolation, powers the field devices, and converts their 4-20mA input signals into isolated 4-20mA output signals, ensuring reliable and safe data transmission in process automation environments.
