It is used for the wireless operation (Start or Stop) of a machine from a distance of a few kilometres. Depending on the propagation conditions, it has a range of up to 15km (line of sight). The commands are sent in absolute encryption and are impossible to break. The PT610 is suitable for remote control of pumps in individual or group irrigation installations in rural areas, where there are difficulties of visual contact or very long distances. The system is also available with the possibility of controlling two, three or four machines from the same remote control (with the corresponding codes PT610D, PT610T, PT610Q) with an additional push button or selector switch.
