Wet node wiring method:
Both NPN/PNP sensors can be connected:
COM can be connected to positive or negative
Dry Node Wiring Method
One end of the customer's switch equipment is connected to the positive power supply of the module, the other end is connected to DI, and the DICOM is connected to the negative power supply of the module.
Detection scheme
1. The module power supply is connected to DI, and the module power supply is negatively connected to DICOM
2. "Module test software.exe" test reading
3. The signal can be read to indicate that the DI function is normal
4. If the signal cannot be read, use a multimeter to measure whether there is a 5-30V voltage across DI and COM
