2.产 品 详 情 资 料：
A-B SK-G9-GDB1-D481 347594-A05自动化控制模块输入模块LED指示灯当离散输入设备关闭时，相应的输入LED应亮起，以指示信号到达模块。如果指示灯未亮起，则可以在模块的接线板或接线板上进行电压检查：如果端子上存在正确的电压，则可以使用编程软件在PLC中检查相应的输入位。A-B SK-G9-GDB1-D481 347594-A05如果软件显示输入位处于逻辑1，则模块的LED电路有缺陷。如果端子上没有正确的电压电平，则可以在输入现场设备处进行检查，以确定设备或互连线路是否有缺陷。如果输入模块的任何输入都不工作，则可能是外部（现场）输入电源有故障、未通电或未正确连接。（输入和输出设备由外部电源供电，而不是从模块内部供电）。输入模块未熔断，因此上图中的保险丝指示灯LED不适用于输入模块。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
