PEPPERL & FUCHS 087721 - Isolated Barrier - Frequency Converter and Switch Amplifier
The PEPPERL & FUCHS KFD2-CD-EX1.32 is an intrinsically safe isolated barrier from the K-System series, engineered for converting and switching frequency signals from NAMUR sensors or dry contacts in hazardous environments. It provides galvanic isolation between the input, output, and power supply, ensuring signal integrity and safety compliance for critical process automation applications. This module integrates both frequency conversion to an analog current output and dual relay switching capabilities for comprehensive signal processing.
