ABB INNPM12网络处理模块工业电路板中文资料：
ABB INNPM12网络处理模块工业电路板N-PE表示中性点和保护接地（PE）之间的电压电势。例如，在中性点高于接地50V的240伏交流系统中，瞬态保护的额定值应为：直流电源连接直流输入接线至AC/DC和直流专用电源直流输入电源的范围24 VDC电源为12至30 VDC，24/48 VDC电源为18至56 VDC，125 VDC电源为100至150 VDC。所有90-30系列电源都具有直流输入功能ABB INNPM12。以下连接信息适用于所有端子：将电源的+和-线连接到端子板上的顶部端子（+连接到顶部端子，-连接到第二个端子）。将顶部的第三个端子连接到系统接地+24 VDC输出（所有电源）底部的两个端子连接到隔离的24 VDC输出，该输出可用于向输入电路供电（在电源的功率限制内）。ABB INNPM12
英文资料
The expression N-PE refers to the voltage potential between neutral and Protective Earth (PE) ground. For example, in a 240 Volt AC system with neutral floating 50V above earth ground, the transient protection should be rated at:DC Power Source Connections DC Input Wiring to AC/DC and DC-Only Power Supplies DC Input power can range from 12 to 30 VDC for the 24 VDC supply, 18 to 56 VDC for the 24/48 VDC supply or 100 to 150 VDC for the 125 VDC supply. All Series 90-30 power supplies have DC input capabilities. The following connection information applies to all of them: Connect the + and - wires from the power source to the top terminals on the terminal board (+ to the top terminal, - to the second terminal). Connect the third terminal from the top to system ground. +24 VDC Output (All Supplies) The bottom two terminals are connected to the isolated 24 volt DC output that can be used to supply power to input circuits (within power limitations of the supply).ABB INNPM12
