Wireless Controls IRRIGATION TECHNOLOGY FOR THE FUTURE THE PURPOSE OF THE NELSON WIRELESS CONTROL SYSTEM is to provide a method of automatically cycling through a series of irrigation control valves in a programmed sequence. While many wireless systems on the market target overall farm automation, data collection, and data management, the TWIG system is specifically designed for automation of irrigation control valves. The TWIG system is sophisticated, yet engineered for simplicity. twigwirelesscontrols.com

Wireless Controls IRRIGATION AUTOMATION Save labor, energy, and water. Improve crop yield and grade. Additional Benefits Costs less than hardwired systems. Eliminates in-ground wire splices which are a chronic source of problems. Reduced lightning damage associated with hard wired systems. Eliminates rodent damage associated with buried wires. Easily expandable to accommodate future system growth by simply adding TWIGs to the network. Solar power option brings automation to remote areas where no power source is available. Makes automation of portable systems possible. There is no limit to the number...

IRRIGATION TECHNOLOGY FOR THE FUTURE » Turns low voltage DC latching solenoids on and off at the command of the TD200 controller » Proprietary “nelson” high powered radio. Adjustable between 902 and 924 MHz. » Three TWIGs available: TWiG-1. Operates one solenoid. TWiG-2. Operates two solenoids, independently. TWiG-4. Operates up to 4 solenoids, independently. » Power source: Two d-cell batteries, good for one irrigation season — shipped with TWiG. » Utilizes a proprietary “deep sleep” cycle technique to minimize power consumption. twig repeater When blind spots or poor communications occur in...

IRRIGATION TECHNOLOGY FOR THE FUTURE Wireless Controls The Nelson Wireless TWIG Control System basically consists of a TD200 Controller capable of controlling up to 100 TWIGs in a programmed sequence. The TWIGs are located in the field on solenoid operated valves. The system operates like a conventional hard-wired automated irrigation system except the underground wires have been eliminated and replaced by two-way wireless radio signals between the TD200 and the TWIGs. The TD200 and the TWIGs that it controls are referred to as a “network”. The TWIG system operates in the 900 MHz range and does...
