Even want to use two mechanical relays after interlocking control of two-way thyristor and then control the motor is reversing, do not know the delay time enough?
Have to use single-chip or ARM, the computer through the serial port to send instructions to the microcontroller, single-chip output control voltage, making the relay opening and closing, and then use the relay control you need mechanical switch. So, you want to buy the equipment is: development board
It depends on where the production of the! Are adjustable with the general minimum is 0.03-0.06
Here to distinguish between categories, the use of occasions, power size, the external circuit, under normal circumstances the relay action time in 20MS or so. There are special in the Us level, there are a few seconds there are delay, depending on the specific model.
