適用范圍：This International Standard applies to particular all-or-nothing electrical relays denominatedsolid-state relays intended for performing electrical operations by single step functionchanges to the state of electric circuits between the OFF-state and the ON-state and viceversa. It is applicable to solid-state relays with rated voltages up to 750 V and with a.c. outputcurrent 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 incorporation in otherproducts or equipment. As such, solid state relays are considered to be components and thisstandard defines the basic safety-related and functional requirements for solid-state relays asstand-alone components.Such solid-state relays are incorporated in products or equipment which themselves have tocomply with the relevant product and/or application standard(s) to meet their intendedapplication. 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.Solid state relays are components (not stand alone devices) and as such do not perform adirect 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 EMCand overcurrent protection, the solid-state relay shall be assessed in accordance with therelevant IEC standard(s).Solid-state switching devices with monolithic structures fall within the scope of IEC subcommittee47E and are not covered in this standard.Semiconductor controllers and contactors fall within the scope of the IEC 60947 series ofstandards – Low-voltage switchgear and controlgear – developed by IEC subcommittee 17Band are not covered in this standard.Compliance with the requirements of this standard is verified by the type tests indicated.
