Toro TDC 2-Wire System Sell Sheet

TDC Series

2-Wire System

Controllers

For an energy efficient, highly cost-effective way to irrigate large
commercial installations, you’ll want the TDC Series from Toro®.

Using a two-wire path to communicate to buried decoders, the
TDC system eliminates high costs associated with traditional valve
wiring, trenching and trouble-shooting. This proven aerospace
technology allows for longer wire runs, smaller-gauge wire sizes
and control of up to 200 stations. TDC systems are upgradeable to
Sentinel® Central Control and the intuitive interface is the best on
the market for simple and straightforward use.

Features & Benefits

New ISP Decoders

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

Rain

Advanced Diagnostics

The TDC systems provide 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.

Stainless Steel
Pedestal Option

With Toro’s EICON Special
Build division, TDC units
may be ordered with a
stainless steel pedestal.
To order please specify
CDEC-PED-50, -100 or -200.

Key-locking
Metal Cabinet

TDC offers a key-locking cabinet
in both the outdoor and indoor
model controllers. Constructed
from heavy-duty powder-coated
metal, this is a wall-mount cabinet
that provides superior weather
and vandalism resistance.

TDC Series 2-Wire System

Upgrade Module

Modular Design

The base model of the TDC offers 50 stations with capability to
easily add another module allowing up to 200-station control. This is
ideal for phased projects. Independently fused wire paths (4 per 100
stations = 8 for 200 stations) provide protection to the controller in
the event of a short in field wiring.
