計(jì)算功耗盡管最大功耗如第A2.1節(jié)“規(guī)范”中的第（1）項(xiàng)“通用規(guī)范”所示，但它實(shí)際上因所安裝模塊的數(shù)量和類(lèi)型而異。閱讀第A2.9節(jié)“模塊電流消耗表”后，根據(jù)以下公式計(jì)算功耗。要估計(jì)面板外殼內(nèi)的溫升，需要計(jì)算面板外殼內(nèi)消耗的總功率。為此，您需要將上述電源模塊的功耗、為FA-M3的I/O模塊提供的外部電源以及安裝在面板外殼內(nèi)的外圍設(shè)備的功耗添加到電源模塊中。下面給出了一些計(jì)算FA-M3輸入/輸出模塊外部電源的示例。示例1：假設(shè)F3XD32-3F的所有點(diǎn)均為ON。每個(gè)點(diǎn)的額定電流輸入為4.1 mA，因此模塊的功耗為：4.1[mA]x 24[V]x 32[points]=3148.8[mW]=3.15[W]示例2：假設(shè)F3GYD64-1F的30個(gè)點(diǎn)為ON，負(fù)載電流為0.1 a。對(duì)于此模塊，必須考慮輸出晶體管的功率損耗。最大接通電壓為0.5 V，每個(gè)晶體管的負(fù)載電流為0.1 A，因此晶體管的功率損耗為：0.5[V]x 0.1[A]x 30[points]=1.50[W]外部電源為24 V/150 mA，因此外部負(fù)載的功耗為：24[V]×150[mA]=3600[mW]=3.60[W'
CE標(biāo)記一致性
關(guān)于CE標(biāo)志CE標(biāo)志旨在整合歐共體內(nèi)各國(guó)現(xiàn)有的安全法規(guī)，確保安全產(chǎn)品的自由流通（移動(dòng)）。制造商或進(jìn)口代理在法律上有義務(wù)在歐共體內(nèi)部流通或銷(xiāo)售的產(chǎn)品上顯示CE標(biāo)志，以表明符合適用于該產(chǎn)品的歐共體指令的要求。每個(gè)EC指令涵蓋一定范圍的設(shè)備；FA-M3必須符合EMC指令（2004/108/EC）和低壓指令（2006/95/EC）。每個(gè)指令僅描述了基本要求；在設(shè)備上顯示CE標(biāo)志之前，設(shè)備制造商需要測(cè)試設(shè)備是否符合適用于設(shè)備的指令。標(biāo)準(zhǔn)結(jié)構(gòu)圖A3.36顯示了CE標(biāo)記標(biāo)準(zhǔn)結(jié)構(gòu)的概念圖。EMC指令（1）EMC指令的要求EMC指令適用于可能發(fā)出電磁干擾的設(shè)備或可能被電磁干擾損壞的設(shè)備。EMC指令要求設(shè)備發(fā)出的電磁干擾不超過(guò)可容忍的水平，并且設(shè)備對(duì)電磁干擾保持最低的抗擾度。本節(jié)總結(jié)了確保FA-M3符合EMC指令的注意事項(xiàng)。但是，安裝制造商需要測(cè)試并確認(rèn)包含F(xiàn)A-M3的成品是否符合EMC指令。
Calculating Power Consumption
Although the maximum power consumption is shown in item (1) "Common Specifications" in Section A2.1, “Specifications,” it actually differs depending on the number and types of modules installed. Calculate the power consumption according to the formulae shown below after reading Section A2.9, “Module Current Consumption Tables.”To estimate the temperature increase within the panel enclosure, you need to calculate the total power consumed within the panel enclosure. To do so, you need to add to the power consumption of the power supply module described above, the external power supplied to I/O modules of the FA-M3, as well as the power consumption of peripheral equipment installed within the panel enclosure. Some examples for calculation of external power supplied to I/O modules of the FA-M3 are given below. Example 1: Assume that all points of the F3XD32-3F are ON. Rated current input per point is 4.1 mA, so power consumption at the module is: 4.1 [mA] x 24 [V] x 32 [points] = 3148.8 [mW] = 3.15 [W] Example 2: Assume that 30 points of the F3YD64-1F are ON with a load current of 0.1 A. For this module, power loss at the output transistors must be considered. The ON voltage is 0.5 V max. and the load current per transistor is 0.1 A, so power loss at transistors is: 0.5 [V] x 0.1 [A] x 30 [points] = 1.50 [W] The external power supply is 24 V/150 mA, so power consumption at external loads is: 24 [V] x 150 [mA] = 3600 [mW] = 3.60 [W]
CE Marking Conformance
About CE Marking CE Marking aims to integrate the safety regulations existing in countries within the EC community and ensure free circulation (movement) of products guaranteed to be safe. A manufacturer or importing agent is legally obligated to display a CE mark on a product circulated or marketed within the EC community showing conformity to the requirements of EC directives that are applicable to the product. Each EC directive covers a certain range of equipment; the FA-M3 is required to conform to the EMC directive (2004/108/EC) and the Low Voltage directive (2006/95/EC). Each directive describes only the essential requirements; an equipment manufacturer is required to test the conformance of equipment to directives applicable to the equipment before displaying the CE Mark on the equipment. ? Standards Structure Figure A3.36 shows a conceptual diagram of the CE Marking standards structure.
EMC Directive (1) Requirements of EMC Directive The EMC directive applies to equipment that may emit electromagnetic disturbances or equipment that may be damaged by electromagnetic disturbances. The EMC directive requires that the electromagnetic disturbances emitted by equipment to not exceed a tolerable level, and that equipment maintains a minimum level of immunity to electromagnetic disturbances. This section summarizes the considerations to ensure that the FA-M3 conforms to the EMC directive. However, the installation manufacturer needs to test and confirm the conformity to the EMC directive of the finished product incorporating the FA-M3.
