PRODUCT DESCRIPTION
PEPPERL & FUCHS 3261610080 - Intrinsic Safety Barrier with Safety Relay Output
This K-System intrinsic safety barrier, identified as KFD2-SR2-EX1.W, provides galvanic isolation for signals originating in hazardous areas. It converts inputs from NAMUR sensors or dry contacts into two independent safety relay outputs for control systems located in the safe area. Engineered for Safety Instrumented Systems (SIS), it facilitates reliable signal transmission for emergency shutdown (ESD) and fire and gas (F&G) applications in process industries.
