Pepperl+Fuchs KCD2-SOT-Ex1.LB Switch Amplifier (214240)

The Pepperl+Fuchs KCD2-SOT-Ex1.LB is a compact 1-channel switch amplifier for intrinsically safe signal transmission from NAMUR sensors or dry contacts in hazardous areas. With 2 passive transistor outputs, it can operate as a signal splitter or error notifier and supports SIL 2 (SC 3) functional safety. Designed for DIN rail installation with only 12.5 mm housing width, it’s ideal for control cabinets with limited space.
