3.1 Description
3.1.1 Input/Output-expansion module SP-SDIO
The module SP-SDIO is an expansion module within the system
samos®PRO and it provides eight safe inputs and four safe outputs.
Features of the SP-SDIO are:
Monitoring of safety switches and sensors.
Transmission of data to the controller module SP-SCON
Receiving of data from the controller module and switching of the
outputs
Fast Shut Off (direct switching of the outputs without data trans-
mission)
The module SP-SDIO does not operate independently. It operates
only in combination with a controller module SP-SCON, see the
configurations-software samos®PLAN.
The simultaneous use of several modules SP-SDIO is possible (up
to twelve modules SP-SDIO and/or SP-SDI overall in the system).
To supply the safe outputs, each input/output-expansion module
must be connected to an external voltage supply.
The module SP-SDIO provides two test signals for a cross
monitoring on the inputs. One test signal is provided on the test-
output X1, the other test signal is provided on the test-output X2.
SP-SDIO detects short circuits between the two
test-outputs (X1, X2), if the duration of the test
pulses is < 4 ms.
If the duration of the test pulses is 4 ms, short

circuits between the test-outputs may remain
undetected.
3.1.2 Input-expansion module SP-SDI
The module SP-SDIO is an expansion module within the system
samos®PRO and it provides eight safe inputs and four safe outputs.
Features of the SP-SDIO are:
Monitoring of safety switches and sensors.
Transmission of data to the controller module SP-SCON
The module SP-SDIO can not operate independently. It operates
only in combination with a controller module SP-SCON; see the
configurations-software samos®PLAN.
The simultaneous use of several modules SP-SDIO is possible (up
to twelve modules SP-SDIO and/or SP-SDI overall in the system).
The supply voltage is provided by the connector of the internal
interface S-BUS+.
The module SP-SDI provides two test signals for a cross
monitoring on the inputs. One test signal is provided on the test-
outputs X1, X3, X5 and X7, the other test signal is provided on the
test-outputs X2, X4, X6 and X8.
SP-SDI detects short circuits between the two
groups of test-outputs (X1, X3, X5, X7) and (X2, X4,
X6, X8), if the duration of the test pulses is < 4 ms.
If the duration of the test pulses is 4 ms, short

remain undetected.
Short-circuits inside of a group of test-outputs (X1, X3, X5, X7) or
(X2, X4, X6, X8) will not be detected.
This has to be observed during the wiring of the safety switches
