martingwb Posted September 16 Share Posted September 16 Hi, I would like to know what Shelly device I can use to control magnetic valves (Rainbird DV, 24 VAC 50/60 Hz, 0,450 A to switch on, 0,25 A to hold permanently) of an irrigation system. I need to control 3 of them so would be great if there is one device that could control all 3 of them (preferred). Thank you, kr, Martin Quote Translate Revert translation?

Is it correct to say that alternatively 3 Shelly 1 Mini Gen3 or 3 Shelly Plus 1 or 2 Shelly Plus 2 PM (to control a total of 4 valves) could be used? Quote Translate Revert translation?

Members thgoebel Posted September 17 Members Share Posted September 17 (edited) Due to SELV requirements, only 3 Shelly plus 1 could do the job in a secure manner. Shelly mini 1 is not SELV compatible, and Shelly plus 2PM contacts are not „dry“ (potential-free). Edited September 17 by thgoebel 1 Quote Translate Revert translation?

wooly Posted September 27 Share Posted September 27 (edited) can you try to supply the 2PM with 24V ? Also, have the three valves be used at same time or cyclically (so only one at maximum active at the same time) ?. Because otherwise would be another winning [for performance and price] solution.

wooly Posted September 30 Share Posted September 30 the question is also: can the valves be driven with 24 V DC ? because some works perfectly, others if you activate with DC remain open, and need a reversed polarity pulse to close.. Actually I have the same problem with my ones that i would like to substitute with a better "smarter" controller: someone here as the project for an external circuit that when closing a switch send a 400ms pulse positive and when the switch is opened send one negative ? without using an externalr relay but all solid state [in this case would be easier to use an UNI that has also temperature humidity wind and light input) Quote Translate Revert translation?
