ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 421202 - Intrinsic Safety Barrier - Control Device
This K-System intrinsic safety barrier, identified as KFD2-CD-EX1.CN, provides galvanic isolation and signal conditioning for controlling field devices in hazardous areas. It functions as a switch amplifier, interfacing digital control signals from the safe area with intrinsically safe loads such as solenoid valves or alarms in classified hazardous locations. Engineered for process automation, chemical, and oil & gas industries requiring robust safety integrity.
