NI PXIe-5646矢量信號(hào)收發(fā)器隔離的24 VDC電源輸出連接電源接線板的底部?jī)蓚€(gè)端子提供到隔離的+24 V DC輸出的連接，該輸出可用于為外部電路提供電源（在電源的功率限制范圍內(nèi)）。警告：如果隔離24 VDC電源過載或短路，可編程邏輯控制器將停止運(yùn)行。所有電源上的公共90-30系列電源功能狀態(tài)指示燈四個(gè)LED位于電源面板的右上方。NI PXIe-5646這些LED的用途如下：PWR頂部的綠色LED（標(biāo)記為PWR）指示電源的工作狀態(tài)。當(dāng)電源具有正確的電源并且工作正常時(shí)，LED點(diǎn)亮；當(dāng)電源故障或未通電時(shí)，LED熄滅。OK（正常）如果PLC運(yùn)行正常，則第二個(gè)綠色LED（標(biāo)記為OK）穩(wěn)定點(diǎn)亮，如果PLC檢測(cè)到問題，則熄滅。運(yùn)行當(dāng)PLC處于運(yùn)行模式時(shí)，第三個(gè)綠色LED（標(biāo)記為運(yùn)行）穩(wěn)定點(diǎn)亮。NI PXIe-5646
英文資料
Isolated 24 VDC Supply Output Connections The bottom two terminals of the power supply terminal strip provide connections to the Isolated +24 volt DC output which can be used to provide power for external circuits (within power limitations of the supply). Caution If the Isolated 24 VDC supply is overloaded or shorted, the Programmable Logic Controller will stop operation.Common Series 90-30 Power Supply Features Status Indicator Lights on all Power Supplies Four LEDs are located on the upper right front of the power supply faceplate. The purpose of these LEDs is as follows: PWR The top green LED, labeled PWR, provides an indication of the operating state of the power supply. The LED is ON when the power supply has a correct source of power and is operating properly, and OFF when a power supply fault occurs or power is not applied. OK The second green LED, labeled OK, is steady ON if the PLC is operating properly, and OFF if a problem is detected by the PLC. RUN The third green LED, labeled RUN, is steady ON when the PLC is in the RUN mode.NI PXIe-5646
