TWIG® Wireless Automation (1st Generation)

The purpose of the TWIG Wireless Control System is to turn irrigation valves on and off, simply and reliably. Period. It eliminates troublesome wires, complicated controls, and impractical features that cause other automation systems to be quickly abandoned. Since its first field trials in 2012, the TWIG system has proven itself as the most reliable and easy to use irrigation automation solution available. It is trusted everywhere from critical industrial dust suppression sites to crop cooling and frost protection.

The system basically consists of a controller, the TD200, that communicates via line-of-sight 900 MHz radio signal with TWIG devices (nodes, or RTUs) that are installed in the field next to solenoid-operated irrigation valves. The TD200 is programmed and operated directly at the display and does not relay on the internet or third party devices for operation. TWIG Repeaters can be added to the radio network to improve poor communications or increase range.

While the next generation TWIG-V and TWIG-MC bring new futures and radio technology to the product line, the TD200 and TWIG remain stalwart performers that will continue to operate in the field for years, with readily available parts and replacement units.
