For the control of up to four 12V latching solenoids where 24V power is not available. Radio communication between the PC and field site (6km line of site or further if multiple radio sites can be used as repeaters). Each iControl 12-Radio (IC12R) can read one standard sensor such as flow, pressure or one multi depth capacitance soil probe. Multiple control or monitoring boards can be linked via cable where more than four solenoids are required to be controlled or where more sensors are required to be monitored. For remote control via radio link.
