IEMMU21 Abb IEMMU21 Infi 90 模块安装单元 后部安装

IEMMU21模块安装单元提供，可安装12个系统模块或10个系统，模块和两个IEPAS02、IEPDS01/02，IEPAF02和IEPDF01/02电源模块。它们还提供I/O扩展器总线、模块总线和控制通道信号；调节电源的分配电压（+5伏、+15伏、-15伏和24伏）；以及一次电源的分配。IEMMU21主电源是为电源模块（IEPAS02、IEPAF02、IEPDS01、IEPDF01、IEPDS02和IEPDF02）安装单元。通常，使用IEPMU01/02的系统会不向安装单元使用分布式主电源。使用模块化电源系统II的系统不允许将分配的主电源分配给安装单元。当机柜配置需要一个带有主配电。当机柜配置需要一个带有配电。

IEMMU21模块安装单元提供可安装12个系统模块；提供I/O扩展器总线、模块总线和控制信号的电气分布；以及调节电源的分配电压（+5 V、+15 V和-15 V）。IEMMU21/22模块安装单元是模块化使用的电力系统II。当机柜配置需要一个没有主机箱的后安装机箱配电。当机柜配置需要没有主电源的前安装机箱时，将使用IEMMU22安装单元分配。


IEMMU21 module installation unit is provided, which can install 12 system modules or 10 system, modules and two IEPAS02, IEPDS01/02, IEPAF02 and IEPDF01/02 power modules. They also provide I/O extender bus, module bus and control channel signals; Adjust the distribution voltage of the power supply (+5V,+15V, - 15V and 24V); And distribution of primary power supply. The main power supply of IEMMU21 is the installation unit for power modules (IEPAS02, IEPAF02, IEPDS01, IEPDF01, IEPDS02 and IEPDF02). Generally, the system using IEPMU01/02 will not use distributed main power supply to the installation unit. The system using modular power supply system II is not allowed to allocate the main power to the installation unit. When the cabinet configuration requires one with main power distribution. When the cabinet configuration requires one with power distribution.
