低压开关设备和控制设备控制器设备接口第1部分:总则

[中文适用范围]： 本部分 IEC 62026 适用于低压开关设备、控制设备和控制器（如可编程控制器、个人计算机等）之间的接口。 本文件不适用于更高级别的工业通信网络，这些网络被称为现场总线，由 IEC 分委员会 65C 负责。 本文件的目的是协调和定义适用于工业 CDI 的一般性质的规则、组件和要求。因此，本文件汇集了各种 CDI 标准中可以视为通用的特性。 对于每个 CDI，需要两个主要文件来确定所有要求和测试： a) 本文件，称为“IEC 62026-1”，在涵盖各种类型 CDI 的相关 CDI 部分中； b) IEC 62026 系列的特定 CDI 部分。 特定 CDI 部分如果不适用，可以省略一般要求，或者在特定情况下可以增加要求，但除非有充分的技术理由，否则不应偏离要求。 注：包含 CDI 的产品的特定要求在产品标准中给出。这些要求附加于本文件中给出的要求。 [外文原描述]： IEC 62026-1:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62026-1:2019 applies to interfaces between low-voltage switchgear, controlgear, and controllers (e.g. programmable controllers, personal computers, etc.). This document does not apply to higher level industrial communication networks that have become known as fieldbuses and are considered by IEC subcommittee 65C. This third edition cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) additional requirements for safety information and instructions, including the measures to be taken, if any, for achieving EMC compliance; b) EMC immunity requirements aligned with current IEC 61000-6 series of standards. Radiated radio-frequency electromagnetic fields test level increased to 6 GHz; c) EMC emissions requirements aligned with current CISPR 11 publication.
