Pepperl Fuchs KFD2-SOT3-Ex2.IO Switch Amplifier (264212)
The P&F KFD2-SOT3-Ex2.IO is a 2-channel intrinsically safe switch amplifier designed to isolate NAMUR sensors or dry contacts in hazardous areas and control non-polarized passive transistor outputs in safe areas.
With galvanically isolated outputs, fast switching capability, line fault detection, and DIP-switch configurable logic reversal, this SIL 2 certified barrier offers precise signal replication and fault transparency for modern control systems.
