KDS water valve

H20 valve wiring


I got this valve here in China for my water control. It is well built and has a small footprint. If loss of power, it will just remain at the whatever state it currently is in. I use a 12Vdc wall wart to power it. Using 2 relays off my M1RB allows me to control it's open and close state. So with constant power it uses 350ma and goes to 410ma while it is operating the valve. It takes 5 seconds for it to close.

Comes in a variety of ID's. Cost to my door was $51.00.




Why do you need two relays from the M1RB? The schematic only shows one.
