Benefits

• Integrated system. Dupline® is the brand name for Carlo

Gavazzi’s 2-wire and 3-wire bus system.

• Cost reduction. The use of a bus system is a proven

way to reduce installation costs – especially when the

distance between I/O points are extensive.

• Fast and easy installation. Completely free topology,

no special cable required, no screen or twist. It can go for

10 km and even further with repeaters.

• High noise immunity. Can run next to power cables.

• Scalability. New modules can be progressively

integrated into the system according to the application

needs.

• Modularity. The system is composed by many modules,

powered by the bus, so that each installation can be

precisely and easily sized.
