Pepperl+Fuchs KFD2‑STC5‑Ex1.20 | 5‑Channel Signal Conditioner | Intrinsically Safe | NAMUR Input | Transistor Outputs
Overview
The Pepperl+Fuchs KFD2‑STC5‑Ex1.20 is a 5‑channel signal conditioner tailored for intrinsically safe (Ex) environments. It accepts NAMUR sensors or dry contacts and provides passive transistor outputs per channel, enabling safe interfacing with control systems while maintaining isolation between field and safe zones. Its compact DIN‑rail design is ideal for space‑efficient installation.
Key Features
-
Five intrinsically safe input channels (NAMUR or dry contact)
-
Five individual passive transistor (open collector) outputs
-
Channel‑level LED indicators for input and output status
-
DIN‑rail mountable housing, 12.5 mm per channel
-
Surge protection and reverse‑polarity protection
-
Fault detection on sensor wire break or short
-
Complies with ATEX and IECEx for Ex ia applications
