ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 219131 - K-System Single-Channel Safety Relay / Switch Amplifier
PEPPERL & FUCHS 219131 is a K-System single-channel switch amplifier with galvanic isolation, engineered for interfacing NAMUR sensors or mechanical contacts situated in hazardous areas (Zone 0, 1, 2) with control systems in the safe area. It provides intrinsically safe input circuits, robust line fault detection, and relay outputs, ensuring high integrity signal transmission for safety instrumented systems and critical process control applications.
