Pepperl+Fuchs KFD0-RSH-1.4S.PS2 Relay Module
Pepperl+Fuchs KFD0-RSH-1.4S.PS2 is a SIL3 rated safety relay module within the K-System family, designed for ESD and fire & gas safety loop interface in hazardous process industries. This safety relay module provides galvanic isolation between 24V DC control side and high voltage load circuit up to 253V AC. The safety relay module supports both ETS energized-to-safe and DTS de-energized-to-safe safety modes, plus DPS dual-pole switching by combining two independent relay outputs. The safety relay module features test pulse suppression, dedicated proof-test input terminals and NAMUR NE44 compliant LED status indication for online functional verification. The safety relay module serves as critical safety spare part for chemical, oil & gas and offshore safety instrumented system cabinet overhaul and ESD/F&G loop retrofit.

This KFD0-RSH-1.4S.PS2 unit is DIN rail mount, loop-powered 24V DC, 20mm slim housing with IP20 protection class. KFD0-RSH-1.4S.PS2 achieves SIL3 certification per IEC 61508, contact rating 253V AC /5A resistive load. KFD0-RSH-1.4S.PS2 has built-in contact welding protection fuse on DTS output channel, suitable for safety shutdown valves, trip relays and fire suppression circuit control. KFD0-RSH-1.4S.PS2 is widely deployed in refineries, petrochemical plants and offshore platforms for safety instrumented system output interface.

As high-integrity safety hardware, this Pepperl+Fuchs relay module guarantees reliable safe-state switching under fault conditions for process safety loops. Pepperl+Fuchs K-System spare parts include KFD0-RSH-1.4S.PS2 safety relays, barrier modules, signal conditioners, terminal blocks and power feed modules for SIS and explosion protection system maintenance. Pepperl+Fuchs SIL safety relay modules are trusted replacement units for legacy ESD and fire & gas safety systems.
