PRODUCT DESCRIPTION
PEPPERL & FUCHS 292461 - K-System Intrinsic Safety Barrier (Switch Amplifier)
This K-System intrinsic safety barrier provides galvanic isolation for interfacing signals from hazardous areas to safe area control systems. It functions as a switch amplifier, converting signals from NAMUR sensors or mechanical contacts located in Zone 0, 1, or 2 into two isolated relay outputs for process control applications.
