Overview
SlimLine Compact modules
SC17.5 and SC22.5 SlimLine Compact modules with screw terminals
SlimLine Compact module SC22.5 with connector with screw terminals
The AS-Interface module series for the control cabinet SlimLine
Compact with degree of protection IP20 creates space in the
cabinet and in distributed local control boxes. A width of just
17.5 mm or 22.5 mm ensures considerable space savings in the
control cabinet.
The SlimLine Compact module series comprises not only digital
and analog I/O modules but also ASIsafe modules with safe
inputs. Digital outputs are available as solid-state and relay
outputs.
Sensors and actuators, as well as the AS-Interface bus cable,
are connected by means of removable screw or push-in spring-
type terminals. Device connectors available as accessories offer
the possibility of looping through the AS-Interface bus cable and
the 24 V DC power supply
U
aux
from one module to additional
modules. This significantly simplifies the wiring, as the
AS-Interface bus cable and
U
aux
only have to be connected to
one device.
All devices for the connection of 3-wire sensors offer the option
of supplying the sensors either from the AS-Interface bus cable
or alternatively from the 24 V DC voltage supply
U
aux
depending
on the requirements of the particular application. A slide switch
is used to make the selection. If supply via U
aux
is selected, the
wiring of the sensor terminals remains unchanged. This means
that no external supply is required for the sensors.
All modules have LEDs on the front that provide diagnostic infor-
mation and indicate the status of the module inputs and outputs.
An addressing socket integrated at the front enables the module
to be addressed also when it is installed. Integrated adapters
permit mounting onto a standard mounting rail
either directly
for the module or for the device connector. Alternatively,
the modules can also be screw-mounted using push-in lugs
(accessories). These lugs for screw fastening must be ordered
separately.
