PEPPERL & FUCHS 192797 - KFD2-CD-EX1.PN Intrinsic Safety Frequency Converter
This K-System intrinsic safety barrier functions as a frequency converter, engineered for reliable signal conditioning from hazardous area sensors. It converts NAMUR sensor or dry contact inputs into isolated analog current and relay outputs for safe area control systems. The module provides intrinsic safety protection for applications requiring frequency monitoring, speed detection, or flow measurement in classified environments.
