EN 60947-5-4:2003

Low-voltage switchgear and controlgear - Part 5-4: Control circuit devices and switching elements - Method of assessing the performance of low-energy contacts - Special tests

IEC 60947-5-4:2002 applies to separable contacts used in the utilization area considered, such as switching elements for control circuits. This standard takes into consideration two rated voltage areas: a) above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion, such as programmable controller inputs; b) below 10 V (typically 5 V) with negligible electrical erosion, such as electronic circuits. This second edition cancels and replaces the first edition which was issued as a technical report in 1996. It now has the status of an International Standard.

Appareillage à basse tension - Partie 5-4: Appareils et éléments de commutation pour circuits de commande - Méthode d'évaluation des performances des contacts à basse énergie - Essais spéciaux

IEC 60947-5-4:2002 s’applique aux contacts séparables utilisés dans le domaine d’emploi considéré, tels que les éléments de commutation pour les circuits de commande. La présente norme prend en compte deux domaines de tensions assignées: a) tensions supérieures (et égales) à 10 V (typiquement 24 V) pour lesquelles les contacts sont utilisés pour commuter des charges avec possibilité d’érosion électrique, par exemple les entrées d’automates programmables; b) les tensions inférieures à 10 V (typiquement 5 V) pour lesquelles l’érosion électrique des contacts est négligeable, par exemple dans les circuits électroniques. Cette deuxième édition annule et remplace la première édition parue comme rapport technique en 1996. Elle a désormais le statut de norme internationale.

Low-voltage switchgear and controlgear - Part 5-4: Control circuit devices and switching elements - Method of assessing the performance of low-energy contacts - Special tests

Ta del standarda IEC 60947 se uporablja za vtične kontakte, ki se uporabljajo na zadevnem območju uporabe, kot so stikalni elementi za krmilne tokokroge.
Ta standard obravnava dva območja nazivne napetosti:
a) nad (in vključno) 10 V (običajno 24 V), pri čemer se kontakti uporabljajo za preklapljanje obremenitev z možnostjo električne erozije, kot so vhodi programirljivih krmilnikov;
b) pod 10 V (običajno 5 V) z zanemarljivo električno erozijo, kot so elektronska vezja.
Ta standard se ne uporablja za kontakte, ki se uporabljajo v zelo nizkoenergetskem območju merjenja, npr. pri sistemih senzorjev in termospojev.
Cilj tega standarda je predlagati metodo ocenjevanja učinkovitosti nizkoenergetskih kontaktov, ob tem pa podaja:
– uporabne definicije;
– splošna načela preskusnih metod za nadziranje in beleženje delovanja kontaktov pri vsakem postopku uporabe;
– funkcionalne podlage za definicijo splošne opreme za preskušanje;
– prednostne preskusne vrednosti;
– posebne pogoje za preskušanje kontaktov, ki so namenjeni za posebne načine uporabe (kot je preklapljanje vhodov računalnika);
– informacije, ki morajo biti navedene v poročilu o preskusu;
– razlago in predstavitev rezultatov preskusa.
