Model: KFD2-SRA-EX4

 

General Information: PEPPERL + FUCHS – SWITCH AMPLIFIER (KFD2-SRA-EX4)

This isolated barrier is used for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area.

Each sensor or switch controls one form A normally open relay contact for the safe area load. A special 2:1 wiresaving technology is available on this isolator, reducing field wiring by 50%.

Switch S1 is used to enable or disable line fault detection of the field circuit. The 2:1 mode is selected with switch S2 while the remaining switches, S3 … S6, are used for reversing the normal output state of the relays.

A unique collective error messaging feature is available when used with the Power Rail system.
