ОПИСАНИЕ ПРОДУКТА
PEPPERL & FUCHS 231225 - K-System Intrinsic Safety Barrier, Signal Conditioner
This device is a K-System intrinsic safety barrier designed for galvanic isolation and signal conditioning of analog current signals in hazardous area applications. It functions as a repeater power supply and input/output converter, ensuring safe operation of field devices located in Zone 0, 1, or 2 by limiting energy to intrinsically safe levels. It is engineered for integration into process control systems requiring robust signal integrity and compliance with international safety standards.
