Pepperl Fuchs KCD2-SON-Ex1 Switch Amplifier (214242)

The P&F KCD2-SON-Ex1 is a 1-channel intrinsically safe switch amplifier with two passive transistor outputs, designed for isolating NAMUR sensors or dry contact signals from hazardous areas to safe zones. The resistive outputs comply with EN 60947-5-6 and enable full line fault transparency (LFT).

With a slim 12.5 mm housing, DIP switch configurability, and SIL 2 compliance, this unit is ideal for space-constrained installations requiring rapid response and built-in fault signaling via Power Rail.
