Twin Decoder Controller

Aquamonix’s TWiN Decoder Controller (Two Wire Irrigation System) is a versatile decoder based control system, that utilizes a two wire system path and can be stand alone or networked to the Aquamonix Central Control System.

The Aquamonix TWiN Controller (Two wire Irrigation system) allows for a range of power input options, so that larger transformers can be used to extend the maximum length of cable runs.   It also allows for multiple output methods to support direct connection to valves, pump start or master valves, reading flow meters, rain switches and other devices, without the need for additional decoders.

The Aquamonix TWiN Controller can be supplied in several easy to specify formats, and can also be supplied in pre-built, pre-tested Project Packs. Our two-wire irrigation system has proved to be reliable and our customers are seeing the benefits.

Our Twin Decoder is suitable for any type of irrigation system. Some of them are:

  • Municipal Park Irrigation
  • Sportsfield Irrigation
  • Golf Course Irrigation
  • Landscape Irrigation
  • Vineyard Irrigation
  • Greenhouse Irrigation
  • Agricultural Irrigation
  • Dust suppression Systems

Whatever your application there is an Aquamonix Controller to suit your requirements.  Consult the Control Solutions Product Guide for standard formats, special builds are available on request for smart irrigation. Or click here  to contact us.
