SAIA PCD3.C100機(jī)械結(jié)構(gòu)和設(shè)計(jì)B 4232-2組裝套件的數(shù)據(jù)表顯示了H41q HR PES的機(jī)械結(jié)構(gòu)和結(jié)構(gòu)。3.4.4 24 V直流電源和配電可向系統(tǒng)H41q HR供電兩次（另見(jiàn)B 4232-2，接線組件套件和第3.8章，I/O電平）。3.4.5 5V直流電源和配電5V直流電源不必單獨(dú)布線，因?yàn)樗呀?jīng)作為子架的一部分安裝。CPU、接口控制和I/O模塊需要5V直流電源。它由帶有F 7130A標(biāo)識(shí)的時(shí)鐘24 V DC/5V DC電源模塊生成。子架配有兩個(gè)電源模塊。電源模塊并聯(lián)。如果其中一個(gè)發(fā)生故障，SAIA PCD3.C100另一個(gè)為PES供電。中央單元監(jiān)控電源模塊（用于CPU、I/O和接口）的5V DC輸出電壓，檢查欠壓和故障。在電源模塊故障的情況下，操作系統(tǒng)通過(guò)系統(tǒng)變量向用戶的程序提供該信息。如果5 V直流系統(tǒng)電源出現(xiàn)故障，中央模塊上的硬件時(shí)鐘和sRAM將由鋰電池緩沖，鋰電池也位于中央模塊上。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
