SD2DUG24 Dupline bus generator Benefits Integrated system. Dupline is the brand name for Carlo Gavazzis 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. Description SD2DUG24 is designed as a cost-effective Plug & Play solution for interfacing Dupline I/Os to control systems. It performs three functions: Dupline channel generator, power supply synchronization (enables 3-wire system with supply) and Modbus RS485 interface. It is fully programmable via software and the software is free downloadable from Carlo Gavazzi website. It substitutes the G34900000xxx and G34960005xxx modules. Applications Dupline is a bus system that offers unique solutions for a wide range of applications in industrial automation, water distribution, energy management, railway systems and many other areas.
