Wiring Diagram
Note: A+ and A- are voltage signal input channels, and AI+ and AI- are current signal input channels. If CH0 needs to be connected to a voltage signal, it can be connected to A+ and A- terminals; if CH0 needs to be connected to a current signal, it can be connected to AI+ and AI- terminals; both channels are CH0 and occupy the same data address, so only one can be selected for use and both cannot be connected simultaneously. The same rule applies to other input channels. The wiring in the diagram is only an example, and specific connections can be made as needed.
