Pepperl+Fuchs KFD2-CD-Ex1.32 | Signal Isolator for Analog Drives,

Pepperl+Fuchs KFD2-CD-Ex1.32 | 1-Channel Signal Isolator for I/P Converters and Positioners

Overview

The Pepperl+Fuchs KFD2-CD-Ex1.32 is a 1-channel isolated barrier that transmits analog signals (current or voltage) from the safe area to hazardous areas. It is typically used to drive I/P converters, positioners, and control valves in explosion-prone environments.

The module ensures precise signal transmission with ≤ 0.1% deviation, and supports current or voltage output, making it a flexible solution in process control applications. Certified for SIL 2, it is ideal for safety-related automation systems.
