      Timer control for DIY RDF

      Actually found these for a non pond related project but thought they might work good for a DIY rdf application.

      If you are using a float switch they have a Single Shot timer that when it sees a switch signal it will turn on for a set amount of time and then turn off until another signal is detected. The timer can be from 0.01s up to 999 hours.

      If you just want to have a preset cycle time they have a cycle timer.
      When input power is applied at startup, the Relay output is energized and the TON timer begins. At the end of the TON time, the output de-energizes and the TOF time begins. At the end of the TOF time, the output is re-energized and the cycle repeats as long as power is applied.
      For $50 its a handy device. And its made in the USA if that is something that's important to you.
