Solenoid valve driver

The utility model provides a solenoid valve driver which comprises an interface unit, a power supply conversion unit, a voltage controller, a drive protective circuit, a solenoid valve interface, a current detecting circuit and a processor which are connected in sequence, wherein the processor is respectively connected to the power supply conversion unit, the drive protective circuit and the display; the processor is further connected to the interface unit through the communication unit; the solenoid valve interface is connected to the processor by a solenoid valve top rod action detecting circuit; the communication unit is connected to the power supply conversion unit. The solenoid valve driver is used for performing protections such as over-current, over-voltage and under-voltage through a signal input to the solenoid valve via the solenoid valve driver, and displaying the corresponding working state of the solenoid valve driver on a display controlled by the processor, so that the solenoid valve driver provided by the utility model can be used for displaying the working states of the solenoid valve driver and the solenoid valve while protecting the solenoid valve.
