PRODUCT DESCRIPTION
PEPPERL & FUCHS 3261610181 - Intrinsically Safe Switch Amplifier with Safety Relay Output
This module is an intrinsically safe switch amplifier from the K-System series, engineered for galvanic isolation and signal conditioning between hazardous area field devices and safe area control systems. It provides reliable switching of non-intrinsically safe loads via dual safety relay outputs, ensuring explosion protection and functional safety in critical process automation applications. The unit supports NAMUR proximity sensors or mechanical contacts in Zone 0/1/2 hazardous environments.
