ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 198744 - KFD2-CD-EX1.32 Isolated Barrier
This is a single-channel isolated barrier from the PEPPERL & FUCHS K-System series, engineered for controlling field devices in hazardous areas from a safe area control system. It provides intrinsic safety for solenoid valves, I/P converters, and alarms, ensuring galvanic isolation and precise signal conditioning for reliable operation in explosive atmospheres. This module facilitates the safe integration of process control signals into hazardous environments.
