2.产 品 详 情 资 料：
要计算输出电路功耗：NI PXI-5651在GFK-0898《Series 90-30 I/O Module Specification Manual》中，找到特定模块的输出电压降值。NI PXI-5651获取连接到模块输出点的每个设备（如继电器、指示灯、螺线管等）所需的电流值，并估计其“接通时间”百分比。要获取电流值，请查看设备制造商的文档或电子产品目录。熟悉设备操作或将要操作的人员可以估计准时率。NI PXI-5651将输出电压降乘以电流值乘以估计的接通时间百分比，得出该输出的平均功耗。NI PXI-5651对模块上的所有输出重复。为了节省时间，您可以确定几个输出在电流消耗和时间上是否相似，这样您只需进行一次计算。NI PXI-5651对机架中的所有离散输出模块重复这些计算。
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. Ŷ Repeat these calculations for all Discrete Output modules in the rack.
