The Irrigander 8 Expander is an 8 zone irrigation expander designed to expand medium size systems that have enough outputs available on the irrigation controller to drive the additional zones. The new Version 2 Irrigander 8 expander is even easier to install and offers even greater expansion capability.

The Irrigander 8 Expander is comprised of two modules: an Encoder that is installed close to the sprinkler controller; a Decoder that is installed close to the valves to be controlled.  The field control wires attached to the irrigation controller's output controlling the valves to be expanded are disconnected and 3 field wires are connected to the 3 outputs on the Irrigander 8 Expander's Encoder. The 8 inputs to the Encoder are connected to any available 8 irrigation controller outputs. The 3 field wires plus the system wide common are connected to the Decoder and the outputs from the decoder are connected to the valves to be controlled (Irrigander 8 Expander diagram). With more than 4 field wires, the Irrigander 8 Expander will use 3 field wires and the system common to control 8 valves allowing the additional wires to be used for additional valves. Detailed specifications and operating instructions are in the User Guide, available below. Application information is available on our Applications page.
