ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 3166070012 - KFD2-SR2-EX1.W.SM Switch Amplifier
The PEPPERL & FUCHS 3166070012 is a K-System series intrinsically safe switch amplifier designed for reliable signal transmission from hazardous areas (Zone 0, 1, 2) to safe areas. It provides galvanic isolation and conditions signals from NAMUR proximity sensors or potential-free contacts, converting them into two independent relay outputs for process control and safety instrumented systems.
