High Light Pepperl+Fuchs KFD2-SR2-Ex1.W.LB isolator 2-channel ，4-20mA hazardous area isolator 24V DC ，Pepperl Fuchs safety barrier with relay

Pepperl+Fuchs KFD2-SR2-Ex1.W.LB Isolator | 2-Channel, 4-20mA, Relay, 24V DC, Hazardous Area

Pepperl+Fuchs KFD2-SR2-Ex1.W.LB isolator specifications. 2-channel, 4-20mA to relay, 24V DC, DIN rail, for hazardous areas.

Product Overview

The Pepperl+Fuchs KFD2-SR2-Ex1.W.LB is a 2-channel isolating signal conditioner designed for use in hazardous areas. It accepts two 4-20mA input signals from field devices and converts each into a relay output. Operating on 24V DC, it provides galvanic isolation between the field (Ex i) and safe-area circuits, enabling alarm generation or logic control. Its DIN rail mountable design makes it a compact solution for panel integration in process control systems.
