PEPPERL & FUCHS 265685 - K-System Isolated Barrier, Frequency Converter
This K-System isolated barrier, identified as KFD2-CD-EX1.30, functions as a frequency converter for intrinsically safe applications. It is engineered to interface frequency-generating field devices located in hazardous areas with control systems in the safe area, providing galvanic isolation and converting pulse inputs into proportional analog current or voltage outputs. This device is critical for process automation, ensuring signal integrity and compliance with intrinsic safety standards in environments such as chemical processing, oil and gas, and pharmaceutical manufacturing.
