Overview
K45 compact modules
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,
however, have a considerably smaller footprint and mounting
depth.
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 shaped cables can
be inserted in the recesses of the mounting plates where they
cause no hindrance.
•
The mounting plate for standard rail mounting
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
比以往任何时候都。黄色和黑色作为接口形状d 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
connections 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 upon the module, the sockets can have a
double assignment.
Pin assignment: Y
i.e. via a socket, two sensors or one sensor/
one actuator is connected.
K45 modules with a maximum of eight digital inputs
These modules have eight digital inputs for connection through
M12 plugs. The sockets have a double assignment
Pin assignment: Y
i.e. via a socket, two sensors or one sensor/
one actuator is connected.
The module requires two AS-Interface addresses for processing
all eight inputs. The addresses can be assigned through a dou-
ble addressing socket integrated in the module.
K45 modules with four digital inputs and outputs/four digital
outputs according to AS-i Specification 3.0
The extended address mode (A/B addresses) according
to AS-Interface Specification 3.0 enables the 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
(instead of only three outputs possible up to now with Specifica-
tion 2.1). Hence with full expansion of an AS-Interface network,
现在有248的输入以及248输出available on one
AS-Interface system.
Please note, however,
•
that these modules can be used only with a master
according to AS-i Specification 3.0
•
that the cycle times for the outputs may be up to 20 ms.
Depending on the module, the sockets can have a double
assignment. Pin assignment: Y
i.e. via a socket, two sensors or
one sensor/one actuator is connected.
