标准摘要
[中文适用范围]: 本国际标准适用于低压开关设备和控制设备开关元件以及控制器(例如可编程控制器、个人计算机等)之间的接口。该标准规定了单个控制电路设备和开关元件之间的面向位的接口系统,通过非屏蔽、非绞合两线电缆连接,承载数据和电源,并建立了具有此类接口的组件互换性的系统。本标准的目的是为此类接口定义: - 从机、主机和机电结构之间的接口要求; ——从机、机电装置和主机的正常使用条件; ——结构和性能要求; - 进行测试以验证是否符合要求。 [外文原描述]: Applies to interfaces between low-voltage switchgear and controlgear switching elements, and controllers (e.g. programmable controllers, personal computers, etc. This standard specifies a bit-oriented interface-system between a single control circuit device and switching elements, connected by a nonshielded, untwisted two-wire cable, carrying data and power, and establishes a system for the interchangeability of components with such interfaces.
英文名称Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 2: Actuator sensor interface (AS-i)
