S-DIAS SDCI Master Module IIO 041
with 4 SDCI ports and 4 digital inputs
The S-DIAS Single-Drop Digital Communication Interface (SDCI)
master module enables the connection of up to 4 intelligent SDCI
sensors or SDCI actuators in compliance with the SDCI
specification V1.1 according to IEC61131-9. All SDCI ports can also
be configured as +24 V digital inputs or +24 V digital outputs. The
module has a 24 V supply connection for powering the SDCI ports
and connected SDCI devices. Additionally, the module has 4
standard +24 V/3.7 mA/0.5 ms digital inputs.
The SDCI devices are configured with the SDCI configuration tool
integrated into LASAL Using the tool, an SDCI configuration file
(IODD) can be loaded for each device and their parameters
defined.

7 Connector Layout
INFORMATION
The connections of the +24 V supply (X5: pin 1 and pin 2) or the GND
supply (X5: pin 3 and pin 4) are internally bridged. To supply the
module, only one connection to a +24 V pin (pin 1 or pin 2) and a GND
pin (pin 3 or pin 4) is required. The bridged connections may be used
for further looping of the +24 V supply and the GND supply. However, it
must be taken into account that a total current of 6 A per connection is
not exceeded by the forward looping!
