ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 088834 - Intrinsic Safety Barrier, Solenoid Driver
This intrinsic safety barrier from the K-System KFD2 series is engineered for the safe control of field devices situated in hazardous areas. It functions as a switch amplifier and solenoid driver, providing a galvanically isolated, intrinsically safe output for actuating solenoid valves, alarms, or LEDs from a safe area control system. The module integrates line fault detection to ensure system integrity and compliance with international explosion protection standards.
