ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 275280 - K-System Intrinsic Safety Barrier Switch Amplifier
The Pepperl+Fuchs KFD2-SR2-EX1.W is a two-channel intrinsic safety barrier from the K-System series, engineered to provide galvanic isolation and signal conditioning for hazardous area applications. It monitors signals from NAMUR proximity sensors or mechanical contacts located in Zone 0/1/2 (gas) or Zone 20/21/22 (dust) and provides isolated relay outputs to the safe area. This device ensures reliable operation and compliance with international safety standards for critical process control systems.
