The range of DN telemetry solutions, with the suitable solenoid control modules can be used for remote control of either 24VAC solenoids or 12VDC latching solenoids. The majority of our clients are tending to move away from cabled irrigation control systems to wireless. Whether being a new development or an existing system, where there are operational issues due to broken cables, the wireless solution offers more flexibility and ease of installation and maintenance.

We are able to provide a range of DN solutions for valve control. The configuration of the system will depend on a number of factors including:

Distance that valves are apart. The DN100 can control 2 valves. The DN200 can control 4 valves and the DN300 can control 8, with the option to add up to 3 additional 8 way expansion boards for a total of 32. So for installations where valves are too far apart to practically run hydraulic tube to valves, the DN100 would be used for single valve control. For sites installations where valves are close together, or where it is practical to run hydraulic tube back to one valve, the DN100 can be used to control 2 valves. The same principle applies for the DN200 and DN300 units.

All DN units can be used for monitoring and control. As an example, if there are two valves within close proximity, the DN200 can control the 2 valves with the other 2 spare channels being used , for example, to monitor a soil moisture probe and a pressure sensor.

For installations where there may be a number of 24VAC solenoids in a pump shed, that are still operating, with some valves are that are either manually operated or have broken cables, the operating 24VAC solenoids in the pump shed can be wired into the DN300, for remote control, and the other field valves can be connected to other field DNs that will communicate via radio. The DN300, if installed in pump shed, in addition to controlling the 24VAC solenoids, can be used to control the pump and monitor relevant parameters, such as pressure and flow.

The “building block” approach to the design of the system allows great flexibility, allowing easy and cost effective expansion and integration of many other control and monitoring solutions.

The web based irrigation scheduling and monitoring package allows users to control, automate and monitor the irrigation system, infrastructure and supporting sensors.
