ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 274120 - K-System Intrinsic Safety Barrier Repeater Power Supply
This K-System intrinsic safety barrier functions as a repeater power supply and signal conditioner, designed for the galvanic isolation and safe operation of field devices in hazardous areas. It provides power to 2-wire transmitters located in hazardous locations while transferring their analog 4-20mA process signals to the safe area, simultaneously offering a digital control path from the safe to the hazardous area.
