Hi
Recently I received 110VAC pneumatic Solenoid Valves from AliExpress, though I had ordered for 12VDC. To save time I decided to use them but here we have 220V 50Hz.
Since the solenoids are very small, I planned to wind a small step down transformer. The question is how do I identify the neutral and live wires from the 110VAC output of the transformer? Or I just connect any one wire directly to the solenoids and the other wire thru relays?
