The
field bus connectors with screw connection
An idea has caught on: the D-SUB connectors SUBCON can be connected
quickly and conveniently under field conditions with-out soldering or
crimping tools. The plug-in contacts are connected to clearly numbered
screw terminal blocks. This produces a systematic overview of the wiring
and simplifies every system start-up.
SUBCON: although the 9-position version is especially suited to
INTERBUS, it can be used for other things as well. A multitude of
further applications are opened up by the fact that all connections are
assigned to one 1 mm2 screw terminal block each. The range
comprises products with the usual numbers of positions: 9, 15 and 25 as
pin or socket versions. The cable entry here is designed for one
cable.
SUBCON-PLUS: if two cable entries are needed, as is the case with
many RS 485 interfaces, there is SUBCON-PLUS. Here too the connections
are led to screw terminal blocks - this time doubled - in other words
for two cables. Only at the end of the bus does the second
termination block remain free for the connection of termination
resistors. The field bus connector can be obtained in the versions M1
and M2, each with a different pin assignment. Application examples can
be found in the table opposite. There are further variants available on
request for special bus systems.
The connectors, designed for the smallest dimensions, are shielded
against EMC influences. An additional lettering area allows each
connector to be labeled individually. Installing the connection block
either in the upper or lower shell makes it possible to introduce the
cable at an angle of 0° to 90° from the right or the left.
