PRODUCT DESCRIPTION
PEPPERL & FUCHS 229332 - K-System Intrinsic Safety Switch Amplifier
This K-System intrinsic safety barrier is a dual-channel switch amplifier engineered for reliable signal conditioning and galvanic isolation between hazardous and safe areas. It facilitates the operation of NAMUR proximity sensors or mechanical contacts located in hazardous locations, providing isolated relay outputs to the control system. Designed for critical process automation, it ensures compliance with intrinsic safety standards for applications in chemical, oil & gas, and pharmaceutical industries.
