PRODUCT DESCRIPTION
PEPPERL & FUCHS 215501 - K-System Intrinsic Safety Barrier, Switch Repeater
This device is a 2-channel intrinsic safety barrier from the K-System series, engineered to interface NAMUR sensors or dry contacts located in hazardous areas with safe area control systems. It provides galvanic isolation and signal conditioning, converting hazardous area signals into safe, isolated relay outputs for reliable process control and monitoring.
