PEPPERL & FUCHS 095912 - K-System Intrinsic Safety Barrier, Switch Amplifier
The PEPPERL & FUCHS KFD2-SR2-EX1.W is a K-System intrinsic safety barrier, specifically a switch amplifier, engineered for the galvanic isolation and signal conditioning of discrete signals originating from hazardous areas. It facilitates the safe interface of NAMUR proximity sensors or mechanical contacts with control systems, providing two normally open (NO) relay outputs for process control in applications requiring intrinsic safety compliance.
