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.
The proximity sensor or switch controls a form C changeover relay contact for the safe area load.
The normal output state can be reversed using switch S1. Switch S2 allows output II to be switched between a signal
output or an error message output. Switch S3 is used to enable or disable line fault detection of the field circuit. During an error condition,
relays revert to their de-energized state and LEDs indicate the fault according to NAMUR NE44.
