Generally, the power line of the DIN style solenoid valve coil has a ground wire, a positive pole and a negative pole. If it is the AC current, the positive and negative poles of the wiring can be ignored; if it is the DC current, you need to pay attention to the positive and negative poles, And the voltage should be the same
