Spark protection barrier Pepperl+Fuchs KFD2-SRA-Ex4

ThePepperl+Fuchs KFD2-SRA-Ex4IS barrier is designed to safely connect and transmit signals between intrinsically safe circuits located in hazardous areas (Zones 0, 1, 2) and standard circuits in non-hazardous areas. This barrier is used to protect and transmit discrete signals from various field devices, such as switches and sensors, operating in environments with an increased risk of explosion. TheKFD2-SRA-Ex4provides reliable protection against overvoltage, short circuits and other potentially hazardous conditions, preventing the risk of sparking and explosion.
