Underhill International introduced its new 2Wire Decoder Module that is fully compatible with Hunter Industries’ new ICC2 commercial controller, expanding its capabilities to two-wire operation.
The 2Wire Decoder snaps directly into the controller module slot and converts an ICC2 to two-wire operation for new irrigation installations or hybrid multiwire/two-wire system expansions. The decoders work with all ICC2 models, including plastic, metal and pedestal cabinets. They can convert the 32-station ICC2 to a 48-station two-wire system.
With Underhill’s modules, standard irrigation wire can be used and grounding is not required along the two-wire path.
In a two-wire system, each valve/field decoder has a unique address that identifies it to the controller. The address signals and 24 VAC power are sent over the same pair of two wires, telling each valve when to open or close.
