PEPPERL & FUCHS 240771100007 - Intrinsic Safety Barrier, Switch Amplifier
This K-System intrinsic safety barrier provides galvanic isolation and signal conditioning for discrete inputs originating from hazardous areas. It functions as a switch amplifier, converting signals from NAMUR sensors or potential-free contacts into a safe, isolated relay output for control systems in the non-hazardous area. Designed for process automation applications requiring compliance with intrinsic safety standards.
