19、g 21 SOLID-STATE RELAYS 1 Scope and object 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 O

20、N-state and vice versa. It is applicable to solid-state relays with rated voltages up to 750 V and with a.c. output current up to 160 A. NOTE Requirements for solid-state relays with d.c. output circuits are under consideration. This standard deals with solid-state relays which are intended for inco

21、rporation in other products or equipment. As such, solid state relays are considered to be components and this standard 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 whi

22、ch 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

23、automation and environmental control; automation and process control; electrical installation engineering; medical engineering; telecommunications; vehicle engineering; transportation engineering; lighting control. Solid state relays are components (not stand alone devices) and as such do not perfor

24、m a direct function. Therefore, no EMC requirements are included in this standard. NOTE This is in line with the European EMC Directive. Where the application of a solid-state relay determines additional requirements such as EMC and overcurrent protection, the solid-state relay shall be assessed in

25、accordance with the relevant IEC standard(s). Solid-state switching devices with monolithic structures fall within the scope of IEC sub-committee 47E and are not covered in this standard. Semiconductor controllers and contactors fall within the scope of the IEC 60947 series of standards Low-voltage

26、switchgear and controlgear developed by IEC subcommittee 17B and are not covered in this standard. Compliance with the requirements of this standard is verified by the type tests indicated. 5 EN 62314:2006The object of this standard is to state: the characteristics of solid-state relays; the require

27、ments which solid-state relays shall comply with reference to a) their operation and behaviour; b) their dielectric properties; c) the degrees of protection provided by their enclosures, where applicable; the tests verifying that the requirements have been met, and the test methods to be adopted; th

28、e information to be given with the solid-state relay or in the manufacturers documentation. 2 Normative references The following referenced documents are indispensable for the application of this document.
