The Pepperl+Fuchs KFD2-SR2-EX1W is a compact intrinsically safe switch relay interface from the K-System, built to ensure reliable signal transfer from hazardous areas to the safe side. It links NAMUR proximity sensors or dry contacts to PLC/DCS inputs with robust isolation and dependable switching performance for process automation.

Designed for high availability in control panels, this module provides galvanic isolation between field and control sides, two independent relay outputs for flexible signal routing, and clear status indication for fast diagnostics. With a wide 20 to 35 V DC supply range, DIN-rail form factor, and screw terminal connections, it integrates quickly into new and existing installations while maintaining stable operation in demanding industrial environments.

Whether standardizing on the Pepperl+Fuchs K-System or upgrading a single loop, the KFD2-SR2-EX1W shortens commissioning and ensures consistent, compliant integration, and it is backed by a 1-year warranty to protect your investment during the first year in service.
