Function: KFA6-SOT2-Ex2
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 de-energized state and LEDs indicate the fault according to NAMUR NE44.
