PRODUCT DESCRIPTION
PEPPERL & FUCHS 301059 - KFD2-SR2-EX1.W Intrinsically Safe Switch Amplifier
The PEPPERL & FUCHS KFD2-SR2-EX1.W (Order No. 301059) is a K-System intrinsically safe switch amplifier designed for the galvanic isolation and control of signals originating from hazardous areas. It provides two independent channels for connecting NAMUR proximity sensors or mechanical contacts, converting their status into two relay outputs for safe area control systems. This device is engineered for functional safety applications, featuring line fault detection and certification up to Safety Integrity Level (SIL) 2.
