To do this, you need to know the current consumption of the solenoid valves. OpenSprinkler has a power consumption of approximately 2.2W = approx. 0.1A. A Rain-Bild solenoid valve has a maximum current of approximately 0.3A I.e. with 4 solenoid valves AT THE SAME TIME you have 4x 0.3A 0.1A = 1.3 A inrush current, the next larger power supply with 1.5A should be used. We have various power supplies in the shop. If you only operate one or two solenoid valves at the same time, you have 2×0.3A 0.1A = 0.7A, a 1A power supply is sufficient. Even if you have 20 solenoid valves but only activate 2 at the same time, that is enough. Note: This is just an example calculation! Please note the technical data of the solenoid valve manufacturer! Note: Total maximum current=3A (fuse) Note: Only applies to OpenSprinkler AC. You can find other suitable power supplies here: Plug-in power supplies AC, Plug-in power supplies DC, DIN rail power supplies AC and DIN rail power supplies DC Never connect more than ONE solenoid valve to ONE OpenSprinkler output! OpenSprinkler can switch several outputs at the same time, so it is not necessary to combine several valves. An AC output can deliver up to 800mA current. If that is not enough, then you should operate the outputs via relays. Version with plastic housing Hardware revision 3.3 and 3.4 supports the W5500 network module with 100MBit interface Temperature working range: -30 to 70 degrees Celsius Note: Product from the USA, delivery times longer if out of stock System requirements Further information (manual, circuit diagram) here: Manual and downloads
