Carlo Gavazzi Automation

Fieldbuses - Agriculture

Carlo Gavazzi's Dupline® bus reduces installation costs and increases flexibility in agricultural irrigation systems, 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 to number or length of branches. One Hi-Line network can handle up to 64 valves over distances of up to 7km, and several networks can be linked together.
