I have a lot of big soviet relays from which I created an irrigtaion control system.

We have one water source, pipe system with valves and 10 separate irrigation channels.

• Activate only one channel at a time - other channels are waiting for their turns.
• Every channel can be configured to one of seven different duration settings from 1 to 30 minutes.
• You can start a channel manually or automatically using the control board.
• Stop button cancels current channel execution.
• If you hold the stop button for more than 5 seconds - the whole system is stopped.

System is assembled from the following soviet relays:

• voltage relays РН-53, РН-54;
• time control relays ВС-10-64, ВС-10-34, РВ-234;
• auxiliary relay РПУ-1
