Time relays for industrial and residential use - Part 1: Requirements and tests

IEC 61812-1:2011 applies to time relays for industrial applications (e.g. control, automation, signal and industrial equipment). It also applies to time relays for automatic electrical controls for use in, on, or in association with equipment for residential and similar use. This edition includes the following significant technical changes with respect to the previous edition: - addition of terms and definitions more commonly used by industry; - addition of timing charts to help explain terms and definitions involving a sequence of events; - addition of provisions for residential use.

Zeitrelais (Relais mit festgelegtem Zeitverhalten) für industrielle Anwendungen und für den Hausgebrauch - Teil 1: Anforderungen und Prüfungen

Relais à temps spécifié pour applications industrielles et résidentielles - Partie 1: Exigences et essais

La CEI 61812-1:2011 s'applique aux relais à temps spécifié utilisés dans les applications industrielles (par exemple: équipements industriels de commande, d'automatisme et de signalisation). Elle s'applique également aux relais à temps spécifié de commandes électriques automatiques utilisées comme éléments constitutifs, auxiliaires ou associés aux équipements utilisés dans des applications résidentielles et analogues. Cette édition comprend les modifications techniques significatives suivantes par rapport à l'édition précédente: - ajout des termes et définitions les plus couramment utilisés dans le secteur industriel; - ajout de chronogrammes permettant de mieux expliquer les termes et définitions impliquant une séquence d'événements; - ajout de dispositions relatives à des applications résidentielles.

Časovni releji za rabo v industriji in bivališčih - 1. del: Zahteve in preskusi

Ta del IEC 61812 velja za časovne releje za uporabe v industriji (npr. nadzor, avtomatizacija, signalna in industrijska oprema). Prav tako velja za časovne releje za avtomatske električne kontrole za uporabo v opremi, na njej ali v povezavi z njo v bivališčih in podobno uporabo. Izraz »rele«, kot se uporablja v tem standardu, zajema vse vrste relejev z nekaterimi časovnimi funkcijami, razen merilnih relejev.
