ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 240777100018 - KFD2-SR2-EX1.W Intrinsically Safe Switch Repeater
The PEPPERL & FUCHS KFD2-SR2-EX1.W is a K-System intrinsically safe switch repeater barrier designed for reliable signal transmission from hazardous areas to safe area control systems. It provides galvanic isolation and features two independent input channels for NAMUR proximity sensors or dry contacts, converting their status into two potential-free relay outputs. This module is engineered for use in Safety Instrumented Systems (SIS) requiring SIL 2 compliance, ensuring robust process safety and operational integrity.
