Par exemple, si vous souhaitez retarder le d\u00e9marrage de diff\u00e9rents moteurs, vous pouvez utiliser un relais temporis\u00e9 pour \u00e9viter qu'une charge de moteur excessive ne provoque un choc \u00e9lectrique sur le circuit principal dans un court laps de temps.<\/span><\/p><p><span style=\"font-weight: 400;\">En utilisant des relais temporis\u00e9s, vous pouvez contr\u00f4ler la charge en fonction d'une s\u00e9quence temporelle, comme le d\u00e9marrage de la charge sur une minuterie, l'allumage et l'extinction cycliques de la charge, le retardement de l'arr\u00eat de la
