ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 084008 - KFD2-SR2-EX1.W.SM Safety Relay / Switch Amplifier
PEPPERL & FUCHS 084008 is a KFD2-SR2-EX1.W.SM safety relay and switch amplifier from the K-System series, engineered for signal conditioning and galvanic isolation of intrinsically safe circuits. It provides two independent channels for monitoring NAMUR sensors or mechanical contacts located in hazardous areas, converting their signals into potential-free relay outputs for use in safe area control systems. This module is designed for applications requiring high functional safety and reliable operation in process automation and safety instrumented systems.
