2.產(chǎn) 品 詳 情 資 料：
A-B SK-G9-GDB1-D481 347594-A05自動(dòng)化控制模塊輸入模塊LED指示燈當(dāng)離散輸入設(shè)備關(guān)閉時(shí)，相應(yīng)的輸入LED應(yīng)亮起，以指示信號(hào)到達(dá)模塊。如果指示燈未亮起，則可以在模塊的接線板或接線板上進(jìn)行電壓檢查：如果端子上存在正確的電壓，則可以使用編程軟件在PLC中檢查相應(yīng)的輸入位。A-B SK-G9-GDB1-D481 347594-A05如果軟件顯示輸入位處于邏輯1，則模塊的LED電路有缺陷。如果端子上沒(méi)有正確的電壓電平，則可以在輸入現(xiàn)場(chǎng)設(shè)備處進(jìn)行檢查，以確定設(shè)備或互連線路是否有缺陷。如果輸入模塊的任何輸入都不工作，則可能是外部（現(xiàn)場(chǎng)）輸入電源有故障、未通電或未正確連接。（輸入和輸出設(shè)備由外部電源供電，而不是從模塊內(nèi)部供電）。輸入模塊未熔斷，因此上圖中的保險(xiǎn)絲指示燈LED不適用于輸入模塊。A-B SK-G9-GDB1-D481 347594-A05
Input Module LED Indicators When a discrete input device closes, the corresponding input LED should light to indicate that the signal reached the module. If the light does not turn ON, a voltage check can be made on the module’s A-B SK-G9-GDB1-D481 347594-A05terminal board or block:If the correct voltage is present at the terminal, the corresponding input bit can be checked in the PLC with your programming software. If the software shows that the input bit is at logic 1, the module’s LED circuit is defective.If the correct voltage level is not present at the terminal, a check can be made at the input field device to determine if the device or interconnecting wiring is defective. If none of an input module’s inputs are working, it may be that the external (field) input power supply is defective, not powered up, or not connected properly. (Input and output devices are powered from an external power supply, not from inside the module). Input modules are not fused, so the Fuse Indicator LED in the previous figure does not apply to them.A-B SK-G9-GDB1-D481 347594-A05
