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
