Dupline® General purpose

In agriculture the Dupline® irrigation bus reduces installation costs and increases flexibility of irrigation systems, where the valves are usually distributed over a large area. In elevator control systems the Carlo Gavazzi’s Dupline® 3-wire bus is a complete solution for the supply ofpower and communication, which is cost-effective method of reducing parallel wiring.

Carlo Gavazzi’s Dupline® 3-wire bus makes elevator control systems simpler and more effective than traditional systems. Space and cost saving I/O-boards with 2 inputs and outputs are mounted in each floor fixture and connected to the push button and lamps. In the elevator car, where the number of signals are higher, boards with multiple I/O’s are used. All the I/O-boards are connected to the same wire cable, which provides both 24VDC power for lamps and floor indicators and serial communication connection with the Dupline® Master Module.


In agricultural irrigation systems Dupline® bus reduces installation costs and increases flexibility, where the valves are usually distributed over a large area. Any type of Irrigation Controller, whether it is a PLC, PC or Dedicated Controller, can use Dupline® as a remote I/O system. The module is available in a housing that allows underground installation, and in a DIN-rail mount housing. The wiring topology is completely free with no limitation in number and length of branches. One Hi-Line network can handle up to 64 valves over distances up to 7km, and several networks can be linked together.
