Overview
SlimLine modules of the S22.5 and S45 series
SlimLine S45 module (left) and S22.5 module (right)
The AS-Interface series of modules for the "SlimLine" control
cabinet with degree of protection IP20 creates space in the
cabinet and in distributed local boxes.
For these modules, the priority was placed on a narrow design.
They have a width of only 22.5 mm or 45 mm.
Standard sensors/actuators and the AS-Interface cable can
be connected using removable screw terminals or spring-type
terminals.
Integrated adapters enable mounting onto a standard mounting
rail. Disassembly from the standard mounting rail is quick and
easy and requires no tools.
With an additional accessory (push-in lugs), the modules can
also be screwed on.
All modules are fitted at the front with LEDs which indicate the
module's status.
An addressing socket integrated at the front enables the module
to be addressed also when it is installed.
In addition to the digital input/output modules, there are modules
of design S22.5 with special functions. These include:
•
Counter modules
•
Ground-fault detection modules
For more information about these modules see

The AS-Interface Specification 3.0 adds a number of completely
new features to the AS-Interface bus system. The extended
address mode (A/B addresses) enables the connection of up to
62 slaves on one AS-Interface network. With the extended
address mode according to Specification 3.0, four outputs are
now possible for the first time even with A/B slaves (instead of
only three outputs possible up to now with Specification 2.1).
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.
Modules with four inputs and four outputs as A/B slaves
according to Specification 3.0 are also available for the control
cabinet as SlimLine S45 modules.
Note:
Please note that the modules according to Specification 3.0 can
be used only with a new master according to AS-Interface
Specification 3.0, and that the cycle times for the outputs must
not exceed 20 ms.
