Oasis Irrigation Controller

The OASIS is the next generation of stand-alone DC irrigation controllers offering 24vAC or 12vDC latch output commands.

The OASIS is an Internet enabled controller, it allows the user to control everything from everywhere via the internet on any platform. (Windows, Linux, Android, iOS…)

The OASIS has Radio Remote Terminal Unit capability (RF RTU). This allows controlling small to medium size projects without wires in the field.

The OASIS is a professional feature packed controller offering the same robustness, user friendliness and low power consumption which our users have grown accustomed to for many years worldwide.
