Digital I/O modules IP67 - K45

Overview
Large K60 compact modules, well-proven in industry, are now
complemented by the new K45 compact module series. They
round off the existing product spectrum at the lower end and
form the basis of a future generation of small compact modules.
The recognized advantages of the existing K60 compact
modules are entirely mirrored in the considerably smaller K45
modules. They have the same base area as the application mod-
ules, but the installed depth is only 2/3 of that of the application
modules and therefore matches the compact module family.
Despite these small dimensions, all modules feature large en-
graving plates and the integrated addressing socket.
Two mounting plates are offered for the K45 compact modules:

The yellow or black and yellow AS-Interface flat cables are laid in the
appropriate cable guides of the mounting plate. They can be inserted in
any direction.

• The first mounting plate has the same hole pattern as the K60
compact module. This means that K60 compact modules can
be mounted flush in combination with K45 modules. The flat
cables are laid without obstructions in the special depressions
in the mounting plates.
• The second mounting plate has the drilled holes and the stan-
dard rail mounting adapter of the application modules.
Installation of the flat cables has been simplified. The yellow and
®
black AS-Interface flat cable can be inserted in the mounting
plates from the left or right depending on the position of the cod-
ing lug. The polarity of the applied voltages cannot be reversed.
The sensors/actuators are connected via M12 sockets. The 4I
module can be ordered as an alternative with M 8 connection
sockets.
The top of the module is located onto the mounting plate.
The top section is fixed to the mounting plate with just one screw.
