Pepperl+Fuchs KCD2-SOT-Ex2 Switch Amplifier (214244)

The Pepperl+Fuchs KCD2-SOT-Ex2 is a 2-channel switch amplifier that transfers digital signals from NAMUR sensors or dry contacts in hazardous areas to a safe area. It features two independent passive transistor outputs and supports reversible mode of operation and line fault detection (LFD). With Power Rail compatibility and a compact 12.5 mm housing, it’s ideal for safety-critical industrial applications.
