Pepperl+Fuchs KFD2‑SR2‑Ex1.W | 2‑Channel Signal Conditioner | Intrinsically Safe | Relay Outputs
Overview
The KFD2‑SR2‑Ex1.W is a high-performance 2-channel signal conditioner, purpose-built for intrinsically safe installations in hazardous areas. It accepts NAMUR sensors or dry-contact inputs from Ex zones and provides galvanically isolated relay outputs to safely drive control systems. Its slim DIN‑rail footprint ensures efficient use of cabinet space.
Key Features
-
Two intrinsically safe input channels for NAMUR or dry contacts
-
Two independent relay outputs (Form A or C) with galvanic isolation
-
LED indicators for input and output status per channel
-
Compact dual-module housing (~25 mm total width)
-
Surge suppression and reverse‑polarity protection
-
DIN‑rail mountable (EN 60715)
-
Certified to ATEX, IECEx, UL, CSA standards for Ex‑ia usage
