ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 301020 - Intrinsic Safety Barrier, Switch Amplifier
This is a single-channel intrinsic safety barrier from the K-System series, specifically the KFD2-SR2-EX1.W model, engineered for galvanic isolation and signal conditioning of discrete signals originating from hazardous areas. It functions as a switch amplifier, converting signals from NAMUR sensors or mechanical contacts into a safe, isolated relay output for control systems in the safe area, while incorporating comprehensive line fault detection.
