The IREL MASTER irrigation controller is the basis of a flexible control system for irrigation systems and other technological equipment.
The use of a large number of digital and analog sensors optimizes system control.
Connecting the controller to the Internet allows the user to control all processes from his personal computer.
The IREL MASTER irrigation controller can service a large number of sprinklers, which allows it to be used in medium and large-sized facilities.
