PRODUCT DESCRIPTION
PEPPERL & FUCHS 115230 - K-System Intrinsic Safety Barrier, Switch Repeater
This K-System intrinsic safety barrier, identified as KFD2-SR2-EX1.W, provides galvanic isolation and signal conditioning for two independent channels originating from hazardous areas. It is engineered to connect NAMUR proximity switches or mechanical contacts in Zone 0, 1, 2 (Gas) and Zone 20, 21, 22 (Dust) environments to safe area control systems. The module features line fault detection and relay outputs for robust process control and safety applications.
