network consists of 4 basic elements: A Central unit, input
modules, output modules and a 2-wire cable. The Central Unit
controls the communication in all DuplineŽ installations. It
sends out the DuplineŽ carrier signal and coordinates all transmission
between input and output modules. Input modules connect to contacts,
voltages and analog signal sources etc. and transmit this information
via the 2-wire cable. Some input modules are sensors with integrated
transducer hence no external signal source is required. Output
modules connect to lamps, contactors, LEDs, instruments etc.
and control these devices according to the information received
via the DuplineŽ network.
