The Irrigander 4/2 Pro Expander is a 4 zone irrigation expander designed to expand medium size systems that have enough outputs available on the irrigation controller to drive the additional zones. The Irrigander 4/2 Pro Expander has two 2-zone decoders allowing 4 valves to be driven in 2 locations. The Irrigander 4/2 Pro Expander uses our proprietary Irrigander 2-wire Technology.

The Irrigander 4/2 Pro Expander is comprised of two types of modules: an Encoder that is installed close to or inside the sprinkler controller; Decoders that are installed close to the valves to be controlled.  One dedicated field wire is attached to the Irrigander 4/2 Pro Expander's output. The 4 inputs to the Encoder are connected to any available 4 irrigation controller outputs. The dedicated field wire and the system wide common wire are connected to the two Decoders and the outputs from each decoder are connected to the valves to be controlled (Irrigander 4/2 Pro Expander diagram). Add optional Irrigander Surge Suppressors to minimize potential damage from lightning. Detailed specifications are in the User Guide, available below. Application information is available on our Applications web page.
