1.3.1. How to extend the Dupline ® bus
1.3.1.1 Network design
Sometimes, in new or in existing installations, there is the need to extend the length of the Dupline®
network beyond the typical Dupline® operative distance. At the same time, it could be necessary to place
some modules at the end of the Dupline® network where a balanced distribution of the modules is not
possible: the cable resistance and load from bus-powered modules result in an excess voltage drop and
might cause the modules placed far from the Dupline® generator not to work properly.
The SB2REP230 module is a 115 to 230 VAC-powered Dupline® repeater and isolator and is the ideal
solution to overcome the problems described above. It also allows the network design to be simplified
and it can be connected to any point on the Dupline® bus.
The picture below shows a simplified wiring diagram between the Dupline® repeater and the Dupline®
generator:
