Pepperl+Fuchs KCD2-SOT-Ex1.LB | 1-Channel SIL 2 Switch Amplifier,

Pepperl+Fuchs KCD2-SOT-Ex1.LB | Single-Channel Isolated Barrier with Transistor Outputs – SIL 2

Overview

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.
