PRODUCT DESCRIPTION
PEPPERL & FUCHS 267075100210 - K-System Intrinsic Safety Barrier Switch Amplifier
This is a two-channel intrinsic safety barrier from the K-System series, engineered to interface switching contacts or NAMUR proximity sensors located in hazardous areas with control systems in safe areas. It provides galvanic isolation and limits energy to intrinsically safe levels, ensuring compliance with explosion protection directives. The unit features two independent relay outputs for signal transmission and status indication.
