IEC 61812-1:20 23作为IEC 61812-1:20 23 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61812-1:20 23适用于工业应用（例如控制、自动化、信号和工业设备）的时间继电器和耦合继电器，以及用于住宅和类似用途设备中、上或与住宅和类似用途设备相关联的自动电气控制。本文档中使用的术语“继电器”包括除测量继电器之外的所有类型的时间继电器和耦合继电器。本文件定义了型式试验和常规试验，以确认服役条件。子条款3.2提供了IEC 61812系列中使用的不同类型时间继电器的定义。IEC 61812-1:20 23取消并取代了2011年发布的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)参考文献的更新；b)增加了风险评估的要求；c)增加了常规试验的要求；d)将条款重新编号，使其排列成更符合逻辑的顺序；e)澄清电击要求；f)增加工业自动化和控制系统的网络安全要求；g)增加环保设计要求；h)添加公共数据字典引用；i)增加继电器类型的术语和定义；j)在标题中添加耦合继电器；k)在范围内添加耦合继电器。

IEC 61812-1:2023 is available as IEC 61812-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61812-1:2023 applies to time relays and coupling relays for industrial applications (for example control, automation, signal and industrial equipment) and for automatic electrical controls for use in, on, or in association with equipment for residential and similar use.
The term “relay” as used in this document comprises all types of time relays and coupling relays, other than measuring relays. This document defines type test and routine test to confirm the service condition. Subclause 3.2 provides definitions for different types of time relays in use in the IEC 61812 series. IEC 61812-1:2023 cancels and replaces the second edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) update of references;
b) addition of requirements for risk assessment;
c) addition of requirements for routine test;
d) renumbering of clauses to bring them into a more logical order;
e) clarification of the requirement for shock;
f) addition of cybersecurity requirements for industrial automation and control systems;
g) addition of environmentally conscious design requirement;
h) addition of common data dictionary reference;
i) addition of terms and definitions of relay types;
j) addition of coupling relays in title;
k) addition of coupling relays in scope.
