16、nal Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic
17、 fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; an
18、y IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standar
19、dization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has repr
20、esentation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IE
21、C cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publi
22、cations. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an
23、 IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal in
24、jury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references
25、 cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for ident
26、ifying any or all such patent rights. International Standard IEC 62314 has been prepared by technical committee 94: All-or- nothing electrical relays. The text of this standard is based on the following documents: FDIS Report on voting 94/232/FDIS 94/235/RVD Full information on the voting for the ap
27、proval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 62314 IEC:2006(E) 5 The committee has decided that the contents of this publication will remain unchanged until the maintena
28、nce result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date.
29、 6 62314 IEC:2006(E) 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
30、-state and the ON-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 i
31、ntended for incorporation 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
32、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 communica
33、tions; building 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 su
34、ch do not perform 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
35、 be assessed in 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 stand
36、ards Low-voltage 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. 62314 IEC:2006(E) 7 The object of this standard is to state: the characteristics of solid-sta
37、te relays; the requirements 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 met
38、hods to be adopted; the 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.
