A Proven Technology with Strong Features
After 16 years of use and with an installed base of more than 100.000 systems, the Dupline fieldbus technology is already well-proven
within industrial applications and water distribution systems. Dupline has become known as an extremely user-friendly, reliable and flexible
fieldbus with the capability to transmit signals over long distances - features that make Dupline ideal as fieldbus for irrigation systems.
System Characteristics
Cable requirements
A single two-wire cable is used for bi-directional communication and power for all the valves in the installation.
There are no special cable requirements, but a min. cross-section of 1.5 m
2
is recommended. Existing cable can be used
Cable Routing
Cable branches can be made freely (free topology)
Valve type
3-wire 12 VDC latching type valves are required
Distance
Max. distance from the Master Module to the farthest valve is 7 km
Number of valves
One Dupline network can handle 64 valves. Up to 32 Dupline networks can be linked, thus enabling control of
2048 valves.
