Pepperl+Fuchs KFD2‑SRA‑Ex4 | 4-Channel Signal Conditioner | Intrinsically Safe | Relay Outputs
Overview
The KFD2‑SRA‑Ex4 is a compact signal conditioner offering relay isolation for up to four NAMUR sensor or dry-contact inputs in hazardous (Ex) areas. It features intrinsically safe input stages and isolated relay outputs to reliably transfer field signals safely to control systems. Designed for efficient DIN-rail mounting, it’s ideal for dense industrial panels in explosive environments.
Key Features
-
Four NAMUR/dry-contact inputs with intrinsic safety
-
Four independent relay (Form C or A) outputs
-
LED status indicators for input and output per channel
-
Galvanic isolation ensures safe separation of zones
-
Space-saving housing (~50 mm total width)
-
Surge and reverse-polarity protection
-
DIN-rail mounting (EN 60715)
-
Certified for ATEX, IECEx, UL, and CSA Ex ia zones
Technical Specifications
