SAI Pro
2.1
Pro Description
The acronym
SAI
stands for
Sensor – Actuator –
Interface
. It is a compact-designed distributor or col-
lector of signal lines.
The SAI Active Universal Pro supplements compact
stand-alone devices with extendable sub-bus mod-
ules.
A Pro System consists of a gateway I/O module and
one or more extension I/O modules.
The gateway I/O is connected to the higher-level
Fieldbus and supplied with power. The gateway I/O
is also the starting point for the sub-bus. With M8
cables, up to fifteen extension I/O modules can be
connected sequentially.
There is a large selection of gateway I/Os for the
common Fieldbus standards. There are also many
different functions within the extension I/O modules.
The maximum expandability of the sub-bus network
is limited by the voltage drop over the line. A de-
tailed explanation of this is included in the manual.
The Pro System is represented as a modular device
in the hardware configuration on the SPS or IPC.
The Fieldbus address and the number and type of
extension I/O modules must be entered here. This
can easily be done with the configuration files which
are available for download from the Weidmueller
homepage.
The gateway I/O consists of the following compo-
nents:
•
An I/O section: to connect the signal lines
•
A settings section: to set the PROFIBUS-DP ad-
dresses and insert the jumpers for the different
electric potentials.
•
A bus / power section: to connect and loop-
through the supply voltage, the Fieldbus interface,
and the sub-bus connection.
