Abstract
A solenoid test device includes a clock circuit, a control circuit, and an output port configured for coupling to two ends of a solenoid. The clock circuit generates a clock signal and sends it to the control circuit. The control circuit periodically and alternately couples one of the two ends of the solenoid to ground via the output port under the control of the clock signal. The solenoid test device is used to generate a periodic control signal to test service life and stability of solenoids.
