Sorry, meant 1017_1, the 8-DPDT relay interface unit, here:
http://www.phidgets.com/products.php?ca ... _id=1017_1 Hopefully the relays each have an "off" position, otherwise I'd think I'd need to use two relays for each valve, one to open and one to close.
The shut off valves would be for 1) whole house water shutoff in case of a leak, and 2) to turn off the water to my pool and pool house when not needed, which is most of the time. There is also set of unused sprinklers that feed off that water supply, and they don't need to stay pressurized. My other sprinklers are controlled via EZFloras.
The actuators need 5 seconds of 12 VDC to rotate the valves. There are separate terminals for open and close. For the whole house shutoff valve, I imagine a water sensor would enable an Indigo trigger, which would then tell the Phidgets device to close the whole house water valve automatically. The "state" would confirm that the valve had closed, and then, when the problem is fixed and the valve reopened, would confirm the valve was fully opened.
For the pool feed, the pool water supply would remain normally closed. When someone wanted to use the pool or pool house, the "Pool On" button would open the valve so that the sinks, john etc would have flow. When done, the valve would be closed, either through a motion sensor timer (automatic) or an Indigo control page button activating the close signal (manual). Again, knowing that the valve was fully closed would be important.
I'm assuming the Phidgets plugin and Indigo can activate/deactivate a relay for 5 seconds. Thanks!
