PP883 3BSE092979R1工控模块系统备件
对于24V DC下的适配器电流消耗，请参阅第3页的DC电源要求。•所用AC-DC转换器的可用电流输出容量。以下示例说明了如何确定可以供电的菊花链通信套件的数量：示例：假设菊花链通信的每个套件都安装了22-COMM-D DeviceNet适配器，并且套件将由输出容量为830 mA的20-XCOMM-AC-PS1转换器供电。由于一个通信套件消耗的电流为60 mA，将电源的可用输出容量除以该消耗（830 mA÷60 mA=13.83），并将结果四舍五入。在本例中，最多可为13个菊花链通信套件供电。交流电源适配器（20-XCOMM-AC-PS1）输入额定输入电压工作输入电压交流输入频率100…240V AC 90…264V AC 47…63 Hz输出输出电压输出电流24V DC 830 mA提示：强烈建议使用双绞线以获得更好的抗噪性。用于美国用于英国用于欧洲用于澳大利亚DSI外部通信套件（22-XCOMM-DC-BASE）AC-DC转换器（20-XCOMM-AC-PS1）…+-+-+-www.rockwellautomation。com Americas:Rockwell Automation，1201 South Second Street，Milwaukee，WI 53204-2496 USA，电话：（1）414.382.2000，传真：（1，传真：（852）2508 1846电力、控制和信息解决方案总部出版物22COMM-IN001E-EN-P–2011年2月PN-105040取代22COMM-IN001D-EN-P-2007年7月版权所有©2011 Rockwell Automation，Inc.保留所有权利。美国印刷。
For adapter current consumptions at 24V DC, see DC Power Supply Requirement on page 3. • Available current output capacity of the AC-to-DC converter being used. The following example explains how to determine the number of daisy-chained Comms Kits that can be powered: Example: Suppose the Comms Kits being daisy-chained each have an installed 22-COMM-D DeviceNet adapter, and that the kits will be powered by the 20-XCOMM-AC-PS1 converter which has an output capacity of 830 mA. Since the current consumed by one Comms Kit is 60 mA, divide the power source’s available output capacity by this consumption (830 mA ÷ 60 mA = 13.83), and round down the result. For this example, up to 13 daisy-chained Comms Kits can be powered.
