Pepperl+Fuchs KFD2-SOT2-EX2 | 214244

Pepperl+Fuchs KFD2-SOT2-EX2 | 2-Channel Intrinsically Safe Signal Isolator – NAMUR Input, Transistor Output

Overview

The Pepperl+Fuchs KFD2-SOT2-EX2 (Part No. 214244) is a 2-channel signal isolator designed for safe processing of input signals from NAMUR sensors or dry contacts in hazardous areas. It transmits these signals as isolated transistor outputs to the safe area, making it an ideal interface between field devices and control systems in Zone 0/1 applications.

With intrinsic safety, DIN rail mounting, and galvanic isolation, this module is widely used in chemical, oil & gas, and pharmaceutical industries.
