To control water levels in dams and reservoirs over long distances.
Float Switch – 2 Wire control:
When the float contact is closed between terminals 5 + 7, the relay is energised – Open to de-energise.
2 Float Switch – 3 Wire control:
Stop float – normally closed contact connected to terminals 6 + 7. Start Float – normally opens across terminals 5 + 6. Closing 5 + 6 energises the relay and remains energised until stop float opens contact between 6 + 7.
Voltage on float terminals = 24V DC.
Distance: Up to 4km long using 1.5mm copper wire cable.
