请注意:此版本的所有临时修订版将在您购买时提供。光学隔离器UL 15771示波器1。1这些要求包括光隔离器，也称为光耦合器或光耦合器:用于在介质隔离电路之间提供单向信号传输，用于电源电压不超过600 V ac rms或dc的设备。1.2这些要求涵盖了光隔离器隔离电路之间绝缘的电气隔离特性。1.3这些要求还包括双保护光学隔离器，该隔离器用于额定电压高达250 V、50或60 Hz的电路，用于无线电、视频和电视设备，以及在光学隔离器故障可能导致火灾、触电或人身伤害的应用中的类似设备。 1.4这些要求不包括光隔离器独立电路的电气特性。1.5这些要求适用于用作设备和器具部件的光学隔离器。如果光隔离器符合这些要求，则不表明该隔离器可在未经进一步调查的情况下作为最终产品的组件使用。1.6包含新特性、特性、组件、材料或系统的产品，或与本标准要求所涵盖的特性、特性、组件、材料或系统不同的产品，对于涉及火灾、触电或人身伤害风险的，应使用适当的附加部件和最终产品要求进行评估，以保持本标准意图最初预期的安全水平。 如果产品的特征、特性、组件、材料或系统与本标准的特定要求或规定相冲突，则该产品不符合本标准。应按照制定、修订和实施本标准所采用的方法，提出并采用要求的修订。

Please note: All interim revisions for this edition available at time of your purchase will be included.Optical IsolatorsUL 15771 Scope1.1 These requirements cover optical isolators, also called optical couplers or photocouplers:Intended to provide unidirectional signal transfer between dielectrically isolated circuits and,Intended for use in equipment with a supply voltage not exceeding 600 V ac rms or dc.1.2 These requirements cover the electrical isolation properties of the insulation between the isolated circuits of the optical isolator.1.3 These requirements also cover double protection optical isolators that are employed in circuits rated up to 250 V, 50 or 60 Hz, in radio, video, and television equipment, and similar equipment in applications in which breakdown of the optical isolator may result in a risk of fire, electric shock, or injury to persons.1.4 These requirements do not cover the electrical properties of the separate circuits of the optical isolator.1.5 These requirements apply to optical isolators for use as components in devices and appliances. Compliance of an optical isolator with these requirements does not indicate that the isolator is acceptable for use as a component of an end product without further investigation.1.6 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
