ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 033808 - KFD2-SR2-EX1.W.SM Intrinsic Safety Barrier Switch Amplifier
This module is a dual-channel intrinsic safety barrier from the K-System, engineered to interface NAMUR proximity sensors or mechanical contacts located in hazardous areas with control systems in the safe area. It provides galvanic isolation and signal conditioning, converting intrinsically safe inputs into potential-free relay outputs for process control and safety applications.
