PRODUCT DESCRIPTION
PEPPERL & FUCHS 216036 - KFD2-SR2-EX1.W.SM Intrinsically Safe Switch Amplifier
This K-System series intrinsically safe switch amplifier provides reliable signal conditioning and galvanic isolation for hazardous area applications. It converts signals from NAMUR proximity sensors or mechanical contacts located in Zone 0, 1, or 2 into a safe, isolated relay output for control systems in the non-hazardous area. Engineered for functional safety, it integrates line fault detection and is suitable for safety instrumented systems up to SIL 2.
