SAIA PCD3.C100机械结构和设计B 4232-2组装套件的数据表显示了H41q HR PES的机械结构和结构。3.4.4 24 V直流电源和配电可向系统H41q HR供电两次（另见B 4232-2，接线组件套件和第3.8章，I/O电平）。3.4.5 5V直流电源和配电5V直流电源不必单独布线，因为它已经作为子架的一部分安装。CPU、接口控制和I/O模块需要5V直流电源。它由带有F 7130A标识的时钟24 V DC/5V DC电源模块生成。子架配有两个电源模块。电源模块并联。如果其中一个发生故障，SAIA PCD3.C100另一个为PES供电。中央单元监控电源模块（用于CPU、I/O和接口）的5V DC输出电压，检查欠压和故障。在电源模块故障的情况下，操作系统通过系统变量向用户的程序提供该信息。如果5 V直流系统电源出现故障，中央模块上的硬件时钟和sRAM将由锂电池缓冲，锂电池也位于中央模块上。SAIA PCD3.C100
Mechanical Structure and Design The data sheet of the SAIA PCD3.C100B 4232-2 assembly kit shows the mechanical structure and design of the H41q-HR PES. 3.4.4 24 V DC Supply and Distribution The supply voltage may be fed two times to the system H41q-HR (see also B 4232-2, wiring assembly kit and chapter 3.8, I/O Level). 3.4.5 5 V DC Supply and Distribution The 5 V DC power supply does not have to be wired separately as it is already installed as part of the subrack. The 5 V DC power is needed by the CPU, the control of the interfaces, and the I/O modules. It is generated by a clocked 24 V DC/ 5V DC power supply module bearing the F 7130A identification. The subrack is equipped with two power supply modules. The power supply modules are paralleled. If one of them fails, the other supplies the PES.The 5 V DC output voltage of the power supply modules (for the CPU, I/O, and the interfaces) are monitored on the central unit checking undervoltage and failure. In case of a faulty power supply module the operating system supplies the user’s program via a system variable with this information. In case the 5 V DC system power fails hardware clock and sRAM on the central module are buffered by a lithium battery which is also on the central module.SAIA PCD3.C100
