Toro GDC 2-Wire System Data Sheet

GDC 2-WIRE

CONTROL SYSTEM

The Toro® GDC System uses innovative technology to provide an irrigation solution to customers who want a
safe, reliable and energy efficient system. Using a two-wire path to communicate to buried control units, the
system eliminates the costs associated with traditional valve wire bundles and provides a solution that is vandal
resistant, easy to install and easy to expand.

Features & Benefits

Lower Costs with Flexible Configurations

GDC Systems can be configured with the modules
located in valve boxes outside of the playing
area for easy access and lower cost, or with the
modules integrated with the sprinkler to reduce
wire and splices.

Less System Downtime with Integrated Surge
Protection (ISP)

ISP 2-wire modules are rated at 20 KV surge
protection—the highest in the industry. In some
of the most active lightning areas of the world,
the GDC provides rock-solid performance.

Easily Expandable Up to 9000 Stations

Whether you have 100, 800 or 9000 stations, the
GDC system will meet your needs and can be
expanded by simply adding modules.

Station-Based Flow Management

Reduces nighttime water window and optimizes
pump efficiency. Central irrigation programs
are available from the hand held radio for
manual watering.

Diagnostics

Built-in diagnostics
automatically let you
know if there are any
problems. The wire path
check quickly confirms
that the whole system is
operational.

Integrated Sprinkler

Toro INFINITY®
and FLEX800™ Series
sprinkler models have
an integrated 2-wire
module option.
