PRODUCT DESCRIPTION
PEPPERL & FUCHS 240779100008 - KFD2-SR2-EX1.W.LB Switch Amplifier / Intrinsic Safety Barrier
The PEPPERL & FUCHS KFD2-SR2-EX1.W.LB is a K-System series switch amplifier and intrinsic safety barrier, engineered for the galvanic isolation and signal conditioning of discrete inputs from hazardous areas. It provides two independent channels for connecting NAMUR sensors or potential-free contacts, converting their status into two isolated relay outputs for safe area control systems, while offering line fault detection capabilities.
