(Main)Solid-state relays
Solid-state relays
This International Standard applies to particular all-or-nothing electrical relays denominated solid-state relays intended for performing electrical operations by single step function changes to the state of electric circuits between the OFF-state and the ON-state and vice versa.
This document deals with solid-state relays which are intended for incorporation in other products or equipment. As such, solid-state relays are considered to be components and this document defines the basic safety-related and functional requirements for solid-state relays as stand-alone components.
Such solid-state relays are incorporated in products or equipment which themselves have to comply with the relevant product and/or application standard(s) to meet their intended application. The following are examples of such applications:
- general industrial equipment;
- electrical facilities;
- electrical machines;
- electrical appliances;
- office communications;
- building automation and environmental control;
- automation and process control;
- electrical installation engineering;
- medical engineering;
- telecommunications;
- vehicle engineering;
- transportation engineering;
- lighting control.
Where the component is intended to be incorporated into the equipment by the final user without EMC knowledge, an assessment for EMC compliance is available. There are no EMC requirements for solid state relays intended for incorporation into the equipment by the equipment manufacturer, because the performance strongly depends on the application into the equipment.
Solid-state switching devices with monolithic structures fall within the scope of IEC sub195 committee 47E and are not covered in this document.
Semiconductor controllers and contactors fall within the scope of the IEC 60947 series of standards - Low-voltage switchgear and controlgear - developed by IEC subcommittee 121A and are not covered in this document.
Compliance with the requirements of this document is verified by the type tests and routine tests indicated.
The object of this document is to state:
- the characteristics of solid-state relays;
- the requirements which solid-state relays shall comply with reference to
a) their operation and behaviour;
b) their 205 dielectric properties;
- the tests verifying that the requirements have been met, and the test methods to be adopted;
- the information to be given with the solid-state relay or in the manufacturer’s documentation.

Relais statiques
L'IEC 62314:2022 s’applique à des relais électriques de tout-ou-rien particuliers appelés "relais statiques", destinés à exécuter des manœuvres électriques par des changements de fonction en une seule étape entre les états bloqué et passant des circuits électriques, et inversement.
Le présent document traite des relais statiques qui sont destinés à être incorporés dans d’autres produits ou équipements. En tant que tel, les relais statiques sont assimilés à des composants et le présent document définit les exigences de base liées à la sécurité ainsi que les exigences fonctionnelles des relais statiques en tant que composants autonomes.
De tels relais statiques sont intégrés dans des produits ou équipements qui se conforment eux-mêmes à la ou aux normes de produit et/ou d’application correspondantes afin de satisfaire à l’application prévue.
Relais statique utilisé en qualité d’appareillage:
Lorsque le relais statique est spécifié comme un appareillage, avec une fonction pour l’utilisateur final, les exigences relatives à la compatibilité électromagnétique (CEM) sont données dans le présent document.
Relais statique utilisé en qualité de composant:
Aucune exigence de CEM ne s’applique aux relais statiques destinés à être intégrés dans l’équipement par le fabricant de l’équipement en question, car les performances dépendent fortement de l’application dans cet équipement.
Le présent document a pour objet de définir:
– les caractéristiques des relais statiques;
- les exigences auxquelles se conforment les relais statiques au regard:
a) de la sécurité électrique;
b) de leur fonctionnement et de leur comportement;
c) de leurs propriétés diélectriques;
d) de la CEM;
– les essais vérifiant que les exigences ont été satisfaites, et les méthodes d’essai à adopter;
– les informations à faire figurer sur le relais statique ou dans la documentation du produit.
Les dispositifs de commutation statiques à structures monolithiques relèvent du domaine d’application du sous comité 47E de l’IEC et ne sont pas couverts par le présent document.
Les gradateurs et les contacteurs à semiconducteurs relèvent du domaine d’application de la série de normes IEC 60947 développées par le sous-comité 121A de l’IEC et ne sont pas couverts par le présent document.
L'IEC 62314:2022 annule et remplace la première édition parue en 2006. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) ajout de catégories de charge pour les charges pour courant continu;
b) ajout d’une catégorie de charge pour les charges du type lampes à ballast intégré;
c) ajout de la connexion "embase";
d) mise à jour des références;
e) introduction de l’exigence de CEM;
f) réorganisation de l’ensemble du document.
