Dupline® is a field- and installation-bus that offers unique solutions for a wide range of applications in building automation, water distribution, energy management, railway systems and many other areas. The system is capable of transmitting multiple digital and analog signals over several km, via an ordinary 2-wire cable. And its modular design and simple operating principle enable even novices to implement its use in new or existing applications. Solutions are engineered by combining products from the wide range of Dupline® modules, including digital and analog I/O modules, PLC and PC interfaces, HMIs and Modems. All modules in an installation connect to the same 2-wire cable which is used to exchange data between modules and between a central controller and modules. Dupline© is typically used as a remote I/O system, creating a link between field devices, such as sensors, contactors, valves, pushbuttons etc. and a central Monitoring Controller, which may be a PLC, PC or the Dupline® Controller. But Dupline® can also be used as a simple wire replacement system where signals are transmitted peer-to-peer without involving a controller or other intelligent unit. The Dupline® signals can be transmitted not only on copper wire, but also on fiber optic cable, via radio modem, on leased telephone lines or via GSM Modem. Dupline® has proven its performance in more than 100.000 installations worldwide since 1986. And even though the latest ASIC technology is used today, the new Dupline® modules are still compatible with those installed 17 years ago.
