Overview
Compact modules K45
The K45 series of compact modules supplements the large K60
compact modules which have a proven track record in industry.
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 K45 modules. The K45 modules
have a substantially smaller basic area and installation depth,
however.
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:
•
Mounting plate for wall mounting
This has a hole pattern that is identical to that of the K60 com-
pact modules. This means that K60 compact modules can be
mounted together with K45 modules in an aligned arrange-
ment. The shaped cables can be inserted in the recesses of
the mounting plates where they cause no hindrance.
•

Connection of the AS-Interface shaped cables
The mounting plate and the compact module are joined together
by means of a screw, with simultaneous contacting of the
AS-Interface cable by the service-proven insulation piercing
method.
Now, mounting the AS-Interface shaped cables is in fact easier
than ever. The yellow and black AS-Interface shaped cable can
be inserted into the mounting plates from the left or right regard-
less of the position of the coding lug. The correct polarity of the
applied voltages is thus guaranteed.
Addressing and connection of the sensors/actuators
Addressing of the K45 compact modules is performed using an
addressing socket integrated in the module. The addresses can
be assigned even when mounted.
K45 modules with a maximum of four digital inputs and outputs
These compact modules contain up to four M12 standard con-
nections or M8 standard connections for inputs and outputs.
Using M12 or M8 standard connectors, a maximum of four
sensors and four actuators can be connected to the compact
module. Depending on the module, the sockets can be
assigned in
duplicate.
Pin assignment: Y
i.e. via a socket, two sensors or one
sensor/one actuator are connected.
K45 modules with a maximum of eight digital inputs
These modules have eight digital inputs for connection through
M12 plugs. The sockets have duplicate assignments.
Pin assignment: Y
i.e. via a socket, two sensors or one
sensor/one actuator are connected.
The module requires two AS-Interface addresses for processing
all eight inputs. The addresses can be assigned through a
double addressing socket integrated in the module.
K45 modules in compliance with AS-i Specification V3.0 with
four digital inputs and outputs/four digital outputs
The extended address mode (A/B addresses) according to
AS-Interface Specification V3.0 enables connection of up to
62 slaves on one AS-i network. With this extended address
mode, four outputs are now possible even with A/B slaves (in-
stead of only three outputs possible up to now with Specification
V2.1). Hence with full expansion of an AS-Interface network,
there are now 248 inputs as well as 248 outputs available on one
AS-Interface system.
Points to bear in mind:
•
These modules can be used only with a master according to
AS-i Specification V3.0.
•
The cycle times for the outputs may be up to 20 ms.
Depending on the module, the sockets can be assigned in
duplicate.
Pin assignment: Y
i.e. via a socket, two sensors or one
sensor/one actuator are connected.
