Relay board

[doxikus]

Ah, now I can see. Ok, maybe to clarify my question, if I buy relayboard (RelayBoardv3), from tinycontrol company, what kind of devices I can control!? Can I use relay to switch devices (ON/OFF) which are powered with 12V DC, 24V or 220 (30)V AC!? Can someone give more info on this topic, maybe example of use with relayboard, tutorial, you have mentioned earlier under Help section of webpage "Watering by Lan Controler" can you give quick info on this practical use,

Again, great product and thanks in advance.
