产品详情资料
简单地使用电源的额定功率(例如30瓦)进行计算,因为应用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90–30系列机架都有自己的电源,因此每个机架都应单独计算。步骤3:离散输出和组合模块的输出计算离散固态输出模块和组合I/O模块的输出电路需要进行两次计算,一次用于模块的信号电平电路(已在步骤1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。要计算输出电路功耗:在第7章或第8章中,找到特定输出或组合I/O模块的输出电压降值。获取连接到模块输出点的每个设备(如继电器、指示灯、电磁阀等)所需的电流值,并估计其“开启时间”百分比。要获取电流值,检查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开机时间百分比
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, you 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 and Combination Modules Discrete solid state Output modules and output circuits of Combination I/O 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.) Since 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. To calculate output circuit power dissipation:In the Chapters 7 or 8, find the value for the Output Voltage Drop for your particular Output or Combination I/O module.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.Multiply the Output
