Exemple d'une opération OU :

Une lampe doit s'allumer, si l’un ou les deux contacts à fermeture sont activés.

Schéma de circuits :

24V

Explication :

La lampe s'allume au moment précis ou l’un ou les deux commutateurs sont activés.

Si le commutateur S1 ou S2 est activé, alors la lampe H1 s'allume.

Circuit de protection de l’automate programmable :

Pour que cette logique puisse être réalisée dans le programme d'automatisation, les deux commutateurs doivent naturellement être reliés aux entrées de l'automate programmable. Ici S1 est relié à l'entrée E 0.0 et S2 à l'entrée E 0.1.

De plus, la lampe H1 doit être reliée à une sortie par exemple A 4.0.
