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