ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 2407800019 - K-System Intrinsic Safety Barrier, 2-Channel Switch Repeater
This K-System intrinsic safety barrier provides galvanic isolation and signal conditioning for two independent digital inputs originating from hazardous areas. It converts signals from NAMUR sensors or potential-free contacts into two potential-free relay outputs for safe area control systems. Engineered for applications requiring compliance with intrinsic safety standards in process automation, chemical, and oil & gas industries.
