标准摘要
[中文适用范围]: 本部分IEC 60947规定了符合IEC 60947-5-2:2019范围的接近设备的要求,这些设备具有模拟输出(PDAO)和/或数字输出,以传输代表检测到的感应输入的相应数字值。这些设备可以提供额外的参数。图1显示了这种设备的原理示意图。它们可能由一个或多个部分组成。 IEC 60947-5-2的要求适用于本文件中规定的接近开关,本文件中的条款编号遵循IEC 60947-5-2的条款编号,必要时进行修改。 本文件不适用于根据IEC 62828系列的工业过程测量变送器。 适用范围产品的典型应用示例: • 工厂自动化和机械行业; • 物流和包装行业; • 输送带、电梯; • 过程工业; • 发电厂。 特殊应用(如腐蚀性环境)可能需要额外的要求。 本文件范围内的产品预计仅由熟练人员选择、安装和维护。 注1:模拟接近设备可以是线性或非线性的。 注2:本文件第5、6和9章中描述的模拟输出接口的具体要求、特性和测试程序基于IEC 61131-2:2017中规定的要求。 [外文原描述]: IEC 60947-5-7:2024 states the requirements for proximity devices that correspond to the scope of IEC 60947-5-2:2019 with analog output (PDAO) and/or a digital output to transmit a corresponding digital value representing the detected sensing input. These devices can provide additional parameters. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) New structure; b) Update and expansion of definitions on analog output properties; c) Expanded performance requirements on analog output; d) Update and new normative references; e) Update of EMC requirements; f) Harmonization with IEC 62828 series; g) Harmonization with IEC 62683 and IEC 61987 definitions; h) Harmonization with IEC 61131-2 requirements; i) Update of the Annex A (former Annex G), Example of the determination of the conformity; j) New Annex B, Overview tests and influence quantities; k) New Annex C, Additional requirements for proximity switches with analog output incorporating a built-in communication interface complying with IEC 61131-9; l) New Annex D, Main characteristics for proximity devices with analog output.
