| Hello all,
I�m helping to design a product with 3 relays to be used in home automation systems. Some of our customers would like to use these relays to trigger their sprinkler systems, so now I�m trying to find out how much voltage and current we need to handle to control any sprinkler system. Do most sprinkler controllers have control lines that our relays could easily be connected to?
Any help would be very much appreciated. |

| auto, Google an irrigation controllers and search their specifications. it should list voltage and current. I believe the controllers source is 110V house voltage and the wires controlling the automatic valve solenoids is 24V. GL Aloha |

| Usually it is 24V AC. The current draw of the solenoids vary, check your specs. I had an older timer that couldn't handle the current draw for a replacement valve, I ended up exchanging the new valve (therefore the solenoid). |

| control relays already exist...... A little pricey tho. http://www.vegetronix.com/Products/Relay-Boards.phtml |
