PRODUCT DESCRIPTION
PEPPERL & FUCHS 421205 - KFD2-CD-EX1.30 Frequency Converter / Switch Amplifier
The PEPPERL & FUCHS 421205, identified as a KFD2-CD-EX1.30, is an intrinsically safe frequency converter and switch amplifier from the K-System series. It is engineered for reliable signal conditioning and galvanic isolation of frequency inputs from hazardous areas, converting them into standard analog current signals and providing two independent relay switch outputs for process control and monitoring applications.
