1.4 Safety notes
Observe the country-specific installation, safety, and accident prevention regulations.
1.4.1 Safety of machines or systems
Draw up and implement
a safety concept
The machine or system manufacturer and the operator are responsible for the safety of the
machine or system and the application in which the machine or system is used. In order to
use the Smart Element described in this document, you must have drawn up an appropriate
safety concept for your machine or system. This includes a hazard and risk analysis in
accordance with the directives and standards specified in Section “Applied directives and
standards” on page 10.
Risk assessment, valida-
tion, and function test
• Before using the Smart Element, perform risk assessment for the machine or system.
• Validate your entire safety system.
• Carry out a new validation every time you make a safety-related modification.
• Perform a function test on a regular basis.
Achievable safety integrity Functional safety is guaranteed for the Smart Element as a single component. However, this
does not guarantee functional safety for the entire machine or system. In order to achieve
the desired safety level for the entire machine or system, define the safety requirements for
the machine or system as well as how to implement them from both a technological and
organizational perspective.
1.4.2 Safety when starting applications
Start conditions Take the following into consideration when determining the start conditions for your machine
or system:
– The machine or system may only be started if it can be ensured that nobody is present
in the danger zone.
– Meet the requirements of EN ISO 13849-1 with regard to the manual reset function.
NOTE: Electrostatic discharge
Electrostatic discharge can damage or destroy components. When handling the device,
observe the necessary safety precautions against electrostatic discharge (ESD) in accor-
dance with EN 61340-5-1 and IEC 61340-5-1.
NOTE: Damage to contacts or malfunction during mounting or removal when
connected
Before performing work on a Smart Element, disconnect the power to the Smart Element.
This means:
• Disconnect the connected I/O devices from the power.
• Switch off the I/O supply voltage UP at the backplane in which the Smart Element is
located.
• Disconnect the communications power supply UL at the bus coupler or controller.

3 Product description
3.1 Short description
The AXL SE PSDI8/3 Smart Element is a safe input module in the Axioline SE product range
for use in a PROFIsafe system.
The Smart Element is suitable for use on an Axioline F backplane. The Smart Element is
integrated in the Axioline F system via the Axioline F backplane.
The Smart Element has four safe digital inputs for 2-channel assignment or eight safe digital
inputs for 1-channel assignment. The inputs can be parameterized in accordance with the
specific application. They enable sensors to be integrated into the safe system.
The Smart Element is configured in the PROFIsafe system using the corresponding engi-
neering tool of the safety controller used.

3.4 Supply voltages
A Smart Element requires the following supply voltages:
– Communications power USE of the Smart Element
– I/O supply voltage UP
The Smart Element receives both supply voltages via the Smart Element interface.
Technical data  See “Communications power of the Smart Elements (USE)” on page 77.
 See “I/O supply UP” on page 77.
3.4.1 Power supply requirements
PELV power supply • Only use power supply units with safe isolation and SELV/PELV in accordance with
EN 50178/VDE 0160.
• Make sure that the output voltage of the power supply does not exceed 32 V even in the
event of an error.
Fuse protection for the
power supply
• Protect the power supply with a suitable external fuse.
• Make sure that the power supply unit is able to supply four times the nominal current
of the external fuse. This ensures that the fuse trips reliably in the event of an error.
3.4.2 Integration of the Smart Elements in the Axioline F system
When integrating Smart Elements in an Axioline F station using an Axioline F backplane:
• Supply the bus head with communications power UL
From here, the UBus communications power for the local bus and the USE communica-
tions power for the Smart Elements are generated.
• Supply the Axioline F backplane with voltage UP
The backplane provides the Smart Elements with this I/O supply voltage.
WARNING: Loss of the safety function
The use of unsuitable power supplies can result in the loss of the safety function.
Observe the additional information and technical data in the documentation for the follow-
ing components:
– Axioline F product range
– Backplane used
– Bus coupler used
See “Documentation for the product range” on page 10.

3.5 Safe digital inputs
Assignment The Smart Element has safe digital inputs which can be used as follows:
– For 2-channel assignment: four 2-channel inputs
– For 1-channel assignment: eight 1-channel inputs
Technical data  See “Safe digital inputs” on page 77.
Parameterization The safe digital inputs of the Smart Element can be parameterized in pairs. This means that
the inputs can be adapted to various operating conditions and different safety integrity levels
can be implemented (SIL, SILCL, Cat., PL).
The achievable safety integrity level (SIL, SILCL, Cat., PL) and error detection depends on
the following:
– Parameterization
– Structure of the sensor
– Cable installation
See “Parameterization of the safe inputs” on page 38.
See “Connection examples of safe inputs” on page 45.

AXL SE PSDI8/3
16 / 84 PHOENIX CONTACT 108928_en_02
3.5.1 Clock outputs OUT_T1 and OUT_T2
The Smart Element has two independent clock outputs. The clock outputs supply the safe
inputs. Both clock outputs provide a pulse pattern if cross-circuit monitoring has been acti-
vated for at least one input pair. The pulse pattern is used to detect cross-circuits in the exter-
nal wiring of the inputs.
 See “Cross-circuit detection” on page 44.
Typical pulse pattern
Figure 3-3 Typical pulse pattern
Key:
Technical data  See “Clock outputs” on page 78.
Behavior in the event of an
error
The clock outputs are also enabled and monitored even when the Smart Element is not
parameterized. If a short circuit occurs at a clock output when it is in this state, the clock out-
put is disabled.
In the event of short circuit to GND or overload of the clock outputs, the clock outputs are
disabled. A diagnostic message is generated. The message is indicated via the SD LED. All
the inputs assigned to the clock output are disabled.
This error must be acknowledged in order to restart the system after the error is rectified.
