Description

OpenSprinkler Zone Expander provides an easy and inexpensive way to increase the number of stations for your OpenSprinkler. Each expander adds 16 zones.

EU, Australian and New Zealand customers: check this page for OpenSprinkler distributors in your region.

NOTE: please choose the correct version:

• If you have OS 3.0 (with built-in WiFi), you must choose Expander 3.0 (AC or DC depending on your main controller version). Please note that there is NO expander for OpenSprinkler Latch — the DC expander will NOT work with OpenSprinkler Latch.
• If you have OS 2.x (with only Ethernet jack), you must choose Expander 2.1 (AC or DC depending on your main controller version).
• If you have OpenSprinkler Pi (OSPi), you must choose Expander 2.1 AC (OSPi only has AC version).

Different expander versions come with different expansion cables, and cannot be plugged into each other: Expander 2.1 comes with a 2×4 wire cable and polarized connector; Expander 3.0 comes with a 2×5 ribbon cable and IDC connector.

Choose AC or DC depending on your main controller (AC controller has an orange terminal block; DC controller has a black-colored power barrel). You can also find out the power version when you reboot the controller, or check the ‘About’ page in the mobile app or web interface.
