TDC 2-Wire System

  • Modular controller up to 200 stations
  • Activate up to 20 solenoids at up to 2.8 miles (4.5 km) away from the controller
  • 10 independent irrigation programs
  • Non-volatile memory requires no batteries and holds programming information for up to five years
The TDC 2-Wire System provides a durable, cost-effective alternative to traditionally wired irrigation control systems. Using a 2-wire path to communicate to buried decoders, the TDC is vandal resistant, easy to install and easy to expand.

New ISP Decoders

Industry leading surge protections up to 20 KV means less grounding in the field than competitive products.

Advanced Diagnostics

The TDC provides true two-way communication with each decoder in the field, thus providing communication verification to decoders in the field, as well as shorted or open solenoid conditions, making troubleshooting a breeze.

Low-Power Operating Costs

The TDC Decoders operate DC Latching Solenoids which utilize no power when valves are in operation.

Water Budget

Water budget by controller, by program and by station (Season Adjust) 0 to 250% in 1% increments.

Simple, Intuitive Programming

Installation and future servicing are quick and simple thanks to the large LCD display and the industry’s most intuitive interface.
