2.產(chǎn) 品 詳 情 資 料：
要計(jì)算輸出電路功耗：NI PXI-5651在GFK-0898《Series 90-30 I/O Module Specification Manual》中，找到特定模塊的輸出電壓降值。NI PXI-5651獲取連接到模塊輸出點(diǎn)的每個(gè)設(shè)備（如繼電器、指示燈、螺線管等）所需的電流值，并估計(jì)其“接通時(shí)間”百分比。要獲取電流值，請(qǐng)查看設(shè)備制造商的文檔或電子產(chǎn)品目錄。熟悉設(shè)備操作或?qū)⒁僮鞯娜藛T可以估計(jì)準(zhǔn)時(shí)率。NI PXI-5651將輸出電壓降乘以電流值乘以估計(jì)的接通時(shí)間百分比，得出該輸出的平均功耗。NI PXI-5651對(duì)模塊上的所有輸出重復(fù)。為了節(jié)省時(shí)間，您可以確定幾個(gè)輸出在電流消耗和時(shí)間上是否相似，這樣您只需進(jìn)行一次計(jì)算。NI PXI-5651對(duì)機(jī)架中的所有離散輸出模塊重復(fù)這些計(jì)算。
To calculate output circuit power dissipation:NI PXI-5651In the Series 90-30 I/O Module Specifications Manual, GFK-0898, find the value for the Output Voltage Drop for your particular module.NI PXI-5651 Obtain the required current value for each device (such as a relay, pilot light, solenoid, etc.) connected to an output point on the module and estimate its percent of “on-time.” To obtain the current values, check the device manufacturer’s documentation or an electronics catalog. The percent of on-time can be estimated by someone familiar with how the equipment operates or will operate.NI PXI-5651 Multiply the Output Voltage Drop times the current value times the estimated percent of on-time to arrive at average power dissipation for that output.NI PXI-5651 Repeat for all outputs on the module. To save time, you could determine if several outputs were similar in current draw and on-time so that you would only have to make their calculation once. ? Repeat these calculations for all Discrete Output modules in the rack.
