ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 281669 - KFD2-SR2-EX1.W Switch Amplifier
This K-System series isolated barrier switch amplifier is engineered for intrinsic safety applications within hazardous industrial environments. It provides reliable signal conditioning and galvanic isolation for NAMUR sensors or mechanical contacts, ensuring safe operation of field devices by limiting energy to intrinsically safe circuits. The module features a single-channel input and a single relay output, suitable for integration into safety-instrumented systems up to Safety Integrity Level (SIL) 2.
