SDI-12 Network Expansion Hub

For use with the AquaLOG range of Instrumentation  
Geotechnical Applications

Part Number:     HUB-SDI12
The HUB-SDI12 is a low cost 6 port SDI-12 network expansion block for use with any SDI-12 based sensors and interface units. This simple device enables the various sensors and interfaces to be easily combined to create many types of system to suit any task.

Any cabling between sensors is reduced enabling simple installation and maintenance to be carried out.
System Assembly

The image opposite shows now a small data logger system is assembled and how the SDI-12 hub simplifies the wiring.

All the different sensors and logger connect to the hub to share signals. Installation and maintenance operations are simplified since sensors can be added or removed by simply un-plugging without the need to disturb any wiring.
