NI PXIe-8108不能简单地使用电源的额定功率（例如30瓦）进行计算，因为应用程序可能不需要电源的全部容量。如果您使用电源端子板上的+24V DC输出，则应计算所消耗的功率，将该值除以2，然后将其添加到电源的总功率中。由于每个Series 90-30机架都有自己的电源，因此每个机架都应单独计算。第3步：离散输出模块的输出计算离散固态输出模块需要两次计算，NI PXIe-8108一次用于模块的信号电平电路（已在第1步中完成），另一次用于输出电路。（继电器输出模块不需要此输出电路计算。）由于这些模块中的固态输出开关设备将降低可测量的电压，因此可以计算其功耗。注意，输出电路消耗的功率来自单独的电源，因此在步骤2中用于计算PLC电源消耗的图中不包括该功率。NI PXIe-8108
You cannot simply use the rating of the power supply (such as 30 watts) for this calculation because the application may not require the full capacity of the power supply. If you are using the +24VDC output on the power supply’s terminal strip, NI PXIe-8108you should calculate the power drawn, divide the value by 2, and add it to the total for the power supply. Since each Series 90-30 rack has its own power supply, each rack should be calculated on an individual basis. Step 3: Output Calculations for Discrete Output Modules Discrete solid state Output modules require two calculations, one for the module’s signal-level circuits, which was already done in Step 1, and one for the output circuits. (This output circuit calculation is not required for the Relay Output modules.) NI PXIe-8108Since the solid state output switching devices in these modules will drop a measurable amount of voltage, their power dissipation can be calculated. Note that the power dissipated by the output circuits comes from a separate power source, so it is not included in the figure used to calculate PLC power supply dissipation in Step 2.NI PXIe-8108
