ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 803114 - KFD2-SR2-EX1.W Intrinsically Safe Switch Repeater Barrier
The PEPPERL & FUCHS KFD2-SR2-EX1.W is a single-channel intrinsically safe switch repeater barrier from the K-System family, engineered for galvanic isolation and signal conditioning of discrete inputs from hazardous areas. It facilitates the safe operation of conventional switches, NAMUR sensors, and other dry contacts located in Zone 0, 1, or 2, transmitting their status to control systems in the safe area while maintaining intrinsic safety.
