Overview

SlimLine modules of the S22.5 and S45 series

The AS-Interface series of modules for the "SlimLine" cabinet

with degree of protection IP20 creates space in the control cab-

inet and in distributed local boxes.

For these modules the priority was placed on a narrow type of

construction. They have a width of only 22.5 or 45 mm.

Standard sensors/actuators and the AS-Interface cable can be

connected using screw-type or spring-loaded terminals.

Integrated adapters enable mounting on a standard mounting

rail. Disassembly from the standard mounting rail is quick and

easy and requires no tools.

With an additional accessory, 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 S22.5 design with special functions. These include:

• Counter module

• Ground-fault detection module

Special Functions

The new AS-Interface Specification 3.0 adds a number of com-

pletely new features to 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 ad-

dress 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 sys-

tem.

Modules with four inputs and four outputs as A/B slaves accord-

ing to Specification 3.0 are also available as SlimLine modules

S45.

Note:

Please note that the modules according to Specification 3.0 can

be used only with a new master according to AS-Interface Spec-

ification 3.0 (e.g. the new DP/AS-i LINK Advanced or IE/AS-i

LINK PN IO) and that the cycle times for the outputs can extend

to max. 20 ms.
