Hi, I'm trying to connect a motorized ball valve to a 5V relay, so I can turn on/off water flow. It has three wires, and this is the image I received when asking the seller about this: https://photos.app.goo.gl/xucvWSWXVV78uYjT8 My impression is that if I connect the blue (N-line) to N-line of the main, the black to the NO and the brown to the NC (and the live wire tot the COM of the relay), then applying a current will turn it on, and turning off the power would result in it turning off (closing the valve)? And since works on 220V, and I'm still not 100% certain after quite a bit of googling, I'd rather ask than just try what I think. |

when you connect 220VAC to black/blue wires, the valve is open; when to brown/blue, it's close. |
