Pepperl+Fuchs KFD0-RO-Ex2 Relay Module (038975)

The Pepperl Fuchs KFD0 RO Ex2 is a compact 2-channel relay output module designed for intrinsically safe control of field circuits. Loop-powered and suitable for safety applications up to SIL 3, this barrier allows galvanically isolated switching of circuits in hazardous areas. Ideal for remote resets, fire alarm tests, or strain gauge calibration switching, it ensures reliable performance in Zone 0, 1, 2, and Div. 1/2 locations.
