Overview
SlimLine modules of Series S22.5 and S45
The AS-Interface module series for the "SlimLine“ control cabinet
to the degree of protection IP20 creates space in the control
cabinet or in the distributed on-site control box.
The emphasis of this module series is on its slim design. The
modules are 22.5 mm or 45 mm in width.
Via screw-type or Cage Clamp terminals, standard sensors/
actuators and the AS-Interface cable can be connected.
Integrated adapters allow the modules to be mounted on stan-
dard rails. Deinstallation from the standard rail is quick and easy
without the need for tools.
The modules can also be screwed in place by an additional
accessory.
All modules have LEDs on the front which indicate the status of
the module.
An addressing socket built into the front allows addresses to be
assigned in the installed state.
Apart from the digital input and output modules, modules with
special functions are also available in S22.5 format. These in-
clude:
• Counter module
• Earth fault detection module
For further information on these modules, see the Section
AS-Interface / Modules with Special Functions.

Design
Removable terminals
The removable terminal is the innovative connection technique
from Siemens for AS-Interface SlimLine modules of the S22.5
and S45 Series. The complete terminal block can be quickly and
easily dismantled and reassembled. It is not necessary to dis-
connect the terminals during this process.
Note
• The devices will be converted from 2004 and will be available
under the same order number.
• Before the terminal block is removed, the device must be dis-
connected from the supply.
Features
• Well-proven terminal system
The complete ease of handling for connecting wires is retained
in the design of the new removable terminals. The familiar con-
ductor cross sections can continue to be used.
• Variable connection techniques
All modules are available with screw-type or Cage Clamp ter-
minals.
• Coding
The terminal blocks cannot be mistakenly interchanged thanks
to coding (EN50178).
• Secured against detachment and vibration
The terminal blocks are latched into the housing. The terminal
blocks can be removed using a screwdriver VDE0100T410
(IEC-4-41). Inadvertent removal is therefore not possible.
• Safety against finger touch
Even in the removed state, the contacts of the modules are safe
against finger touch according to DIN 61140(IEC 60529).
• Labeling
All terminal connections are labelled on the terminal block
which makes preassembly possible.
