A
fieldbus system normally provides very efficient and
fast communication when you have all the connected equipment
in a single building of limited size. As soon as your
system is spread over a wide area and maybe also in a
harsh environment you need to use communication equipment
for extension and protection. A 4-wire modem with different
serial interfaces (RS-232/V.24 and RS-422/485) and a
balanced current loop interface makes it possible to
extend the lines and build very complex bus-systems.
The LD-01/02 enables 9 600 bit/s at distances of up to
2.5 km and the possibility to connect either RS-232/V.24
or RS-422/485 interfaces to the network. The modem/line
sharing unit gives your system complete galvanic isolation
and ensures that connected equipment will not be disrupted.
