Ti-240 Two Wire Controller

An easy to install user friendly two wire system with an unparalleled level of reliability.

Base model supports up to 240 valves but can be easily expanded to support up to 640 valves. Patented optical technology protects against electrical and lightening surges. Convenience of standalone or option to operate through your PC, tablet or Smartphone.

  • Easy to Expand -  Simply connect a decoder at the nearest point along the 2 wire cable where it is needed. Additional cable drivers, each supporting up to 240 valves can be added.
  • Additional Inputs - A range of additional inputs can be added e.g. digital inputs, flow meter inputs or switched inputs.
  • Built in Decoder Protection - Decoders have their own surge suppression, thermal trip and are fully waterproof.
  • Reliable Communication -Communication between decoders and the controller is tolerant to poor cabling and earth leakages. Standard grease filled crimps can be used for joining the cable and decoders.
  • Easy to Use - Large LCD display and menu driven displays.
  • Extensive Optional Features List  - Select the features you want from a list of options. The features will then appear in the controller’s Main Menu for you to use.
  • Extensive Program Options - Name valves,  up to 12 valves in parallel, 64 auto starts, irrigate on time or volume.
  • Sensors - Integrate  with our sensors, weather stations and dosing systems.
  • Irrigation Control Options - Irrigation can be controlled by light, rain, temperature, humidity, wind speed, wind direction or flow meters.
  • Flexible Operation - Standalone or operation through smartphone, tablet or PC.
