Two-wire controls send both power and signal to multiple irrigation valves over a single pair of wires.
SAN MARCOS, Ca. – Hunter Industries has released the Dual, a two-wire control system for its I-Core controller platform. The release is the latest entry in the fast growing “decoder” or “two-wire” segment of the irrigation control market.
Two-wire controls send both power and signal to multiple irrigation valves over a single pair of wires, with the ability to activate any individual valve. Due to their simplicity, ease of expansion, and long distance performance two-wire decoder systems have been making major inroads in the commercial control market. Until now, they had primarily been associated with higher-end, large-scale irrigation control systems.
The Dual plug-in for the I-Core controller creates a two-wire alternative for designers and installers who may have shied away from more exotic control systems.
A Two -Wire System for All
The Dual product family is a new generation of Hunter designed control products, which target smaller systems and first-time installers of decoder technology. A Dual output module can be inserted in the output slots of any I-Core controller. The module then provides up to three two-wire paths to the field for two-wire valve control via individual decoders in the valve boxes.
The Dual decoder module may even be combined in the same controller with conventionally wired valves.
The Dual system can operate up to 48 zones via a single pair of wires, at distances up to 7,500 feet (2.3 km). The 48 zones can all be installed on a single path, or divided over multiple paths to take advantage of pipe trenches.
The Dual system includes the Dual 48M decoder output module, which is added to the I-Core controller, plus two new field decoder modules (Dual-1 and Dual-2) and a surge suppression module (Dual-S) for lightning protection. The decoder output module is also used to program the station numbers into field decoders.
