PEPPREL+FUCHS KFD2-DWB-EX1.D Safety Barrier

The Pepperl+Fuchs KFD2-DWB-Ex1.D is a rotation speed monitor that detects overspeed and underspeed conditions of a digital signal from a hazardous area.�It does this by comparing the input frequency to the user-programmed reference frequency. When an overspeed or underspeed condition is detected, the relay outputs signal this condition.�
