Fraba optical sensors Signal conditioning unit
The evaluation unit can monitor up to two safety contact strips OSE.
The output relay contacts (terminals OSE 33/34) open, if one of the safety edge is operated.
A distinction between the safety contact strips is not possible
After the output relay will open a reversal
contact (terminals Rev 23/24) closed for a short time.
So that the re-drive of the door can be initiated.
Can be used for gates 12978 according to the standards EN 12453 and EN.
