Pepperl+Fuchs KCD2-SOT-Ex1.LB

The KCD2-SOT-Ex1.LB is a 1-channel isolated barrier from Pepperl+Fuchs for transmitting digital signals from hazardous areas to the control side. Accepting input from NAMUR sensors or dry contacts, it provides two passive transistor outputs and offers line fault detection (LFD) and SIL 2 safety compliance. It is ideal for intrinsically safe circuits in chemical, oil & gas, and process automation environments.

◆ Key Features:

• Input Type: NAMUR sensor or mechanical contact

• Output Type: 2 × passive transistor outputs (NPN open collector, short-circuit protected)

• Power Supply: 24 V DC (19–30 V DC range)

• Signal Splitting Function: 1 input to 2 outputs

• LFD (Line Fault Detection): Built-in, monitors for open or short circuit

• SIL Certification: SIL 2 (SC 3) per IEC/EN 61508

• Housing Width: Only 12.5 mm – space-saving design

• Mounting: DIN rail (EN 60715)
