PEPPERL & FUCHS 235622 - K-System Single Channel Safety Relay for Intrinsically Safe Applications
This K-System safety relay, identified as KFD2-SR2-EX1.W.SM, provides galvanic isolation and signal conditioning for intrinsically safe circuits in hazardous areas. Engineered for functional safety applications up to Safety Integrity Level (SIL) 3, it monitors discrete signals from NAMUR sensors or mechanical contacts and provides a safe relay output for control systems in the non-hazardous area. Its robust design ensures reliable operation in critical process automation and emergency shutdown systems.
