PEPPERL+FUCHS Switch Amplifier KFA5-SOT2-Ex2 Intrinsic Safety Barriers Isolated Barriers K-System
Switch Amplifier KFA5-SOT2-Ex2
· 2-channel isolated barrier

· Dry contact or NAMUR inputs
· Passive transistor output, non-polarized
· Line fault detection (LFD)
· Reversible mode of operation
· Up to SIL 2 acc. to IEC 61508
Function :
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 proximity sensor or switch controls a passive transistor output for the safe area load.
The normal output state can be reversed using switch S1 for channel I and switch S2 for channel II. Switch S3 enables
or disables line fault detection of the field circuit.
During an error condition, the transistors revert to their deenergized state and LEDs indicate the fault according to NAMUR NE44.
