SRI – Smart Remote Irrigation is a unique radio control systems. The SRI RTU System includes Remote Terminal Units (RTUs), Radio and Software which provide continuous wireless monitoring,

control and long distance communication abilities. This modular system provides reliable and consistent results which allow integration with the PLC – Spirit Pro Controller and GreenLine HMI Software. Each unit can act as a repeater which provides the ability to overcome obstacles in the field to allow commands and information to be sent across great distances.


The SRI is a sophisticated field unit for operating of 1 – 12 DC latch solenoids.

The SRI can read various sensors digital and analogue inputs (4-20mA).

The SRI RF capability enables reliable, low energy, long distance communication with the main system controller by using state of the art Mesh communication.

The SRI is powered from miniature integrated solar panel and rechargeable battery.
