■ Overview
The K45 compact modules are the ideal supplement to the K60
large compact modules, which have proven their worth in indus-
try. They are the logical consequence for rounding off the bottom
end of the existing product range.
The acclaimed advantages of the existing K60 compact mod-
ules are fully emulated by the much smaller K45 modules. Their
footprint is the same as that of the user modules. However, they
have a mounting depth which is only two-thirds of the user mod-
ule and hence an exact match for the compact module family.
Yet in spite of these small dimensions all the modules have large
labels and an integrated addressing socket.
Two mounting plates are offered for the K45 compact modules:
• The mounting plate for wall mounting has a hole pattern that is
identical to that of the K60 compact modules. This means that
K60 compact modules can be mounted together with K45
modules in an aligned arrangement. The flat cables can be
inserted in the recesses of the mounting plates where they
cause no hindrance.
• The mounting plate for standard rail mounting has a hole
pattern that is identical to that of the user modules.
Mounting the flat cables is now easier than ever. The yellow and
black AS-Interface flat cable can be inserted into the mounting
plates from the left or right regardless of the position of the cod-
ing lug. The correct polarity of the applied voltages is always
guaranteed.
Sensors/actuators are connected using M12 sockets.
The 4E module can be ordered optionally with M8 connection
sockets.
