The PSS universal (PSSu) from Pilz is
a modular system for use in the
decentralised periphery of plant and
machinery. A modular PSSu type
system consists of:
` One head module
` At least one supply voltage
module
` Input/output modules for standard
and failsafe applications, which
may be installed in any sequence
` End bracket at the start of the
system to secure the system on
the mounting rail
` Terminating plate with integratable
end bracket at the end of the
system to secure the system on
the mounting rail
Head module
` Connects the sensor/actuator
level for standard applications to
master controllers via various
standard bus systems (e.g.
PROFIBUS)
` Connects the sensor/actuator
level for failsafe applications to
SafetyBUS p
` Co-ordinates the entire process
data traffic for standard and
failsafe applications
` Permits a failsafe output to be
switched via a standard signal,
depending on an enable from a
failsafe signal (local enable
principle)
Supply voltage modules
` Available for various functions
` Consist of an electronic module
and a base module
Input/output modules
` Available for a wide range of
input/output functions
` Consist of an electronic module
and a base module
Base modules
` Carrier units for the supply voltage
and input/output modules
` Used to connect the field wiring
` Available with the following
connection types:
- Cage clamp terminals or
- Screw terminals
Electronic modules
` Are plugged into base modules
` Can be inserted/removed
The module bus is formed by
arranging the base modules together
and connecting them via a
mechanical latch.
` Data
2 independent bus systems are
available for FS data and ST data.
The data is processed in the head
module.
` Module supply
Supply for the head module and
the electronic modules. Various
supply voltage modules are
available for different functions
(e.g. voltage refresh, separating
the supply).
` Periphery supply
The supply for the actuators (load)
or input test pulses is provided at
the base module contacts,
depending on the function of the
electronic module. Various supply
voltage modules are available for
different functions.
The connection on the module
bus can be disconnected in order
to form supply groups. In this
case it is necessary to use an
appropriate supply module, which
disconnects the supply (module
supply, periphery supply and Crail supply) to the preceding (lefthand) modules and provides a
new supply to subsequent (righthand) modules.
` C-rail
The C-rail is routed through all the
base modules via the module bus.
The C-rail is an additional power
rail, which is attached to the base
module connections. It is intended
as an option, providing additional
power if required.
Access to the C-rail is available
through the use of base modules
which contain the letter “C” in
their description (e.g. PSSu BP1/8 S). The base module
connections on which the C-rail is
available are marked with a black
bar across the whole connection
level. I/O modules normally route
the C-rail connections on
connection level 3.
If the supply is separated on base
modules containing supply
modules, this is symbolised by the
fact that only the right-hand
connection on the connection
level is marked with a black bar.

Explanation
Details are valid for designing a PSSu
system with any combination of ST
modules and FS modules, provided all
the following conditions are met.
Details are valid for designing a PSSu
system with ST modules only.
Restrictions may apply, depending on
the standard bus system that is used.
Details are valid for designing a PSSu
system with FS modules only.
Details are valid for designing a PSSu
system with dual-pole FS output
modules only
(e.g. PSSu E F DI OZ 2).
The load is determined by the current
consumption of the head module and
electronic modules that are used. If a
heavier load arises, an additional supply
module must be used to refresh the
module supply. Further details can be
found in the description of the relevant
supply module.
The module bus rail for periphery supply
can take a max. 10 A load. If a heavier
load arises, an additional supply module
must be used to refresh the periphery
supply. The load is determined by the
current consumption of the sensors/
actuators on the electronic modules that
are used. Further details can be found in
the description of the relevant supply
module.
The C-rail can take a max. 10 A load. If a
heavier load arises, an additional supply
module must be used. Further details
can be found in the description of the
relevant supply module.

Basics
System description
Local enable principle
The new local enable principle
technique means that outputs on
failsafe output modules can now be
switched via a standard bus system
(e.g. PROFIBUS).
Configuration of the local enable
principle
` Via the PSS WIN-PRO system
software
` By configuring FS output modules
for the relevant standard bus
system (e.g. in the case of
Profibus, included in the GSD file)
` By assigning an FS output to a bit
in the ST process image of
outputs (ST-PIO). The FS output
will therefore operate as an enable
output.
` Ability to read the FS inputs via
the standard bus system.
Operation of the local enable
principle
` The configured FS outputs are
driven via a standard bus system.
` Provided the enable output carries
a “1” signal, the configured FS
outputs can be driven via a
standard bus system.
As soon as the enable output
carries a “0” signal, the configured
FS outputs are shut down safely.
Control via the standard bus
system is ignored.
The connections on the base
modules are indicated via two-digit
numbers. The first digit denotes the
column on the module. The second
digit denotes the connection level
within the PSSu system.
Example:
Colour marking of connection levels
Colour marking of connection levels
The colour marking on the different
connection levels is helpful when it
comes to wiring. Various colour
markers are available to label the
connection levels. For the connection
diagram to remain consistent it
makes sense to arrange I/O modules
of the same type into groups (see
example).
The connection levels are typically
assigned as follows:
` Connection level 1 and 4
On I/O modules, connection levels
1 and 4 typically contain the
module’s inputs or outputs.
Marking in the example:
- Black [3]
` Connection levels 2 and 3
On I/O modules, connection levels
2 and 3 typically contain the
common supplies (+24 VDC, test
pulse outputs, 0 VDC).
Marking in the example:
Supply groups are formed by
separating the 24 V supply (periphery
supply) and, if necessary, also the
5 V supply (module supply). In this
case it is necessary to use a supply
module that disconnects the supply
(periphery supply, C-rail supply and,
if necessary, the module supply) to
the preceding (left-hand) modules
and provides a new supply to
subsequent (right-hand) modules.
Provided an appropriate base
module is used, in principle any
electronic supply voltage module is
suitable for separating supplies.
Principle:
Formation of supply groups for
periphery supply
In each case you should take note of
the description of the relevant
electronic supply voltage module.
For example, supplies can be
separated on the following modules:
Modules

used (e.g. vertical installation),
there will be certain restrictions
with regard to
- Ambient temperature
Optimum upward heat
dissipation can no longer be
guaranteed.
- Vibration and shock stress
There will be increased
requirements on the system
fastenings: use additional
metallic end brackets!
Mounting rail
` A PSSu system is designed to be
installed on a zinc plated DIN rail
in accordance with DIN EN 50022.
Dimensions:
35 x 7.5 mm or 35 x 15 mm
` Where vibration and shock stress
place increased requirements on
the system fastenings, it is
recommended that the mounting
rail is screwed to the mounting
plate approximately every
200 mm.
Module layout
` The first module on a PSSu
system is always a head module.
` A supply voltage module is always
connected to the right of the head
module
- To supply the module electronics to the head module and
subsequent I/O modules
- To provide 24 VDC for the
periphery supply
` Next right it is possible to install
I/O modules for FS and ST
applications.
- The I/O modules (input
modules, output modules) can
be installed in any order.
- I/O modules for FS applications
and ST applications can be
combined as required.
- In various applications it makes
sense to combine specific
modules into groups.
- It is not possible to mix base
modules with screw terminals
and cage clamp terminals.
- The max. number of I/O
modules is determined through
the defined system limits.
` Supply voltage modules may be
required to refresh the supply to
the module electronics. This can
be determined through the
defined system limits.
` To form supply groups, an
additional voltage supply module
is required at the start of each
group. The modules belonging to
the supply group will then follow
to the right.
` The final element in a PSSu
system is always a terminating
plate, containing the bus
terminating resistors.
` Various fastening elements are
used at the start and end of the
system to secure the system on
the mounting rail:
- End bracket at the start of the
system
- Plastic version (standard)
- Metal version
(increased requirements with
regard to vibration and
shock stress)
- End bracket at the end of the
system
- Plastic version (standard)
- Metal version

followed on the right by a base
module that is suitable for an
appropriate supply voltage
module.
` The wiring should preferably be
carried out after the base modules
are installed, but before the
electronic modules are installed.
` Please note:
- For mechanical reasons it is not
possible to mix base modules
with screw terminals and base
modules with cage clamp
terminals.
- All contacts should be
protected from contamination.
` Procedure:
The same procedure applies for all
base modules (e.g. base modules
in grid widths 1 x 12.6 mm, 2 x
12.6 mm).
- Base modules should always
be installed to the right of the
head module.
- Slot the groove on the base
module on to the mounting rail
from below [1].
- Push the base module back [2]
until you hear it lock into
position.
- On the mounting rail, slide the
base module to the left until
you hear the two lateral
mounting hooks on the
adjacent module (head module
or base module) lock into
position [3].
Installing a terminating plate and end
bracket at the end of the system
` Select an end bracket, depending
on the vibration and shock stress
- Plastic version of end bracket
(integrated into terminating
plate)
- Additional end bracket if
required (metal version)
` Procedure:
- Use a screwdriver for slottedhead screws (M2).
- Attach the terminating plate to
the mounting rail as the final
element on the system [1].
- Loosen the fixing screw on the
end bracket until the terminals
are far enough apart for the end
bracket to be positioned on the
mounting rail.
- Place the end bracket on the
mounting rail, to the right of the
terminating plate [2].
- Slide the end bracket and
terminating plate into each
other [3]
- Slide the terminating plate with
integrated end bracket up to
the final base module as far as
it will go [4]; ensure that contact
is made with the integrated bus
terminating resistors.
- Insert the screwdriver into the
terminating plate [5]
- Tighten up the integrated end
bracket [6].
` If an additional end bracket (metal
version) is required to secure the
system, this additional end
bracket is installed to the right of
the terminating plate.
Procedure:
- Loosen the fixing screw on the
metallic end bracket
- Place the metallic end bracket
on the mounting rail
- Slide the metallic end bracket
up close to the terminating
plate with the integrated end
bracket
Removing a terminating plate and
end bracket at the end of the system
` Procedure:
- Use a screwdriver for slottedhead screws (M2).
- Insert the screwdriver into the
terminating plate [1]
- Loosen the fixing screw on the
end bracket [2].
- Move the terminating plate and
integrated end bracket to the
right [3].
Note: Do not damage the
elements used to connect to
the adjacent base module.
- Loosen the fixing screw on the
end bracket until the terminals’
clamping force is lifted.
- Remove the terminating plate
and integrated end bracket
from the mounting rail.
Modules may be inserted and
removed a maximum of 20 times.
After this point a correct contact can
no longer be guaranteed.
` Electronic modules should only be
plugged into base modules that
are installed and, preferably,
wired.
` Electronic modules with outputs
(output modules) may only be
inserted or removed when the
load is switched off.
If modules are inserted/removed
under load, the possibility of the
PSSu system switching to a safe
condition (STOP condition) cannot
be excluded. The corresponding
I/O-Group (SafetyBUS p) may also
switch to a STOP condition.
[2]
` Procedure:
- The electronic module must
audibly lock into position [1].
- Identify the electronic module
using the labelling strips [2]
Electronic modules have a two-part
coding element. The first time an
electronic module is plugged into a
base module, one part of the coding
element remains on the electronic
module, while its counterpart is fixed
on to the base module.
The coding element is designed to
help prevent plugging errors (e.g.
when exchanging modules).
` Once a base module has been
coded, only electronic modules
with the same coding can be
inserted.
` If a new electronic module is to be
plugged into a base module that
has already been coded, you will
initially need to remove the coding
counterpart on the electronic
module.
Overview of the mechanical coding
elements on electronic modules
Ensure that a correct contact is
made. A correct contact can no
longer be guaranteed when modules
have been inserted and removed
more than 20 times.
` Electronic modules with outputs
(output modules) may only be
inserted or removed when the
load is switched off.
If modules are inserted/removed
under load, the possibility of the
PSSu system switching to a safe
condition (STOP condition) cannot
be excluded. The corresponding
I/O-Group (SafetyBUS p) may also
switch to a STOP condition.
When modules are attached to the
mounting rail, contact with the
mounting rail is made via a contact
spring. The mounting rail should be
earthed appropriately.
A special earthing terminal that can
be attached to the mounting rail is
available as an accessory.
The system is configured using Pilz
configuration software.

Explanation
The load on the module supply is
determined by the current consumption
of the head module and electronic
modules that are used.
A PSSu E F PS supply module provides
a max. module supply of 1.5 A.
If a heavier load arises, an additional
supply module must be used to refresh
the module supply.
- Module supply error
If the lower voltage limit is
exceeded, a status message is
sent to the head module and
the “5 V” module LED (see
table)
- Periphery supply error
If the upper/lower limits of the
monitored parameters are
exceeded, a status message is
sent to the head module and
the “24 V” module LED (see
table)
- Module error
If a module error occurs (e.g.:
error at the inputs, error in
programming mode,
communication error), a status
message is sent to the head
module and the “Err” module
LED (see table)
- SafetyBUS p error
All the outputs in the affected
I/O-Group are shut down safely
and the I/O-Group switches to
a STOP condition. The error is
entered in the head module’s
error buffer.
Supply voltage
` The supply voltages for module
supply and periphery supply may
be in the range of +18 VDC ... +30
VDC. Safe operation cannot be
guaranteed outside this range.
` Safe electrical isolation must be
ensured for both the external 24 V
supplies. Failure to do so could
result in electric shock.
` Power supplies must conform to
EN 60950, 03/97, section 2.3, EN
60742, 9/95 or EN 50178, 10/97.
` To achieve the lowest possible
residual ripple (< ± 1.2 V), we
recommend that you install a
three-phase bridge rectifier or an
electronically regulated supply.
` If failsafe inputs are used, the
connection between “Ground”
(0 V periphery supply) and the
earth bar or earth fault monitor
must be in accordance with
relevant national regulations (e.g.
EN 60204-1, NFPA 79:17-7, NEC:
Article 250).
` On the module bus, the load
current of max. 10 A must not be
exceeded for the periphery
supply.
` A total current of max. 10 A must
not be exceeded on the C-rail.
Wiring
` Connect together the 0 V
connections on all the 24 V power

Electronic module for switching the
periphery supply on non-safetyrelated input/output modules
arranged in blocks. For safetyrelated functions
Approvals
PSSu E F BSW
In progress
Module features
` Housing width: 25.2 mm
(2 x grid width)
` 24 VDC infeed for periphery
supply (24 VDC)
` Infeed to C-rail supply (if required)
` Failsafe switching on/off of the
periphery supply (+24 VDC, 0 V)
(block switching)
` LED indicators for:
Module error
` Details of the base modules that
can be used are available under
“Base modules” and “Order
reference”
Module description
The module meets the requirements
of EN IEC 61508 and EN 954-1
Category 3. The module may be
used for safety-related switching of
the periphery supply on non-safetyrelated output modules (standard
modules).
If the module is used in conjunction
with non-safety-related modules it is
possible to achieve Category 3 in
accordance with EN IEC 61508 and
EN 954-1.
` Max. switchable current at 25°C:
8 A
Safety features
The module meets the following
safety requirements:
When the relevant base module is
used, the connection to the
incoming (left-hand) periphery
supply and C-rail is interrupted on
the module bus. The following
supply is then provided on the
module bus for subsequent (righthand) modules:
- Periphery supply (24 VDC, max.
8 A) for subsequent modules
(right-hand side)
- C-rail supply for subsequent
modules (right-hand side)
` Each output block requires its
own block switching module.
` The relationship between the
switchable load current and the
operating temperature is
illustrated in the derating curve
below (see graph). The operating
point should be on or below the
characteristic curve.
` The periphery supply is switched
on/off via the controller’s user
program.
` The periphery supply is switched
off if a module error is detected.
` The module is generally used to
switch the periphery supply safely
on standard modules that are
arranged in blocks.
` Any modules following an output
block (on the right-hand side) will
require a new voltage supply of
their own.
- If an error occurs, the block
switching module switches off
the periphery supply to
subsequent (right-hand)
modules.
` SafetyBUS p error reaction:
If an error occurs, all the outputs
in the affected I/O-Group are shut
down safely and the I/O-Group
switches to a STOP condition. The
error is entered in the head
module’s error buffer.
System configuration
The system is configured using Pilz
configuration software.
Addressing the outputs
The outputs are addressed using Pilz
PSS WIN-PRO system software.
Supply voltage
` The supply voltages for module
supply and periphery supply may
be in the range of +18 VDC ... +30
VDC. Safe operation cannot be
guaranteed outside this range.
` Safe electrical isolation must be
ensured for the external 24 V
supplies. Failure to do so could
result in electric shock.
` The power supply must conform
to EN 60950, 03/97, section 2.3,
EN 60742, 9/95 or EN 50178,
10/97.
` To achieve the lowest possible
residual ripple (< ± 1.2 V), we
recommend that you install a
three-phase bridge rectifier or an
electronically regulated supply.
` The external periphery supply
must be able to provide a load
current of max. 10 A. On the
module bus, the load current of
max. 8 A must not be exceeded
for the periphery supply.
` The load current of max. 10 A
must not be exceeded on the Crail.
Wiring
` Connect together the 0 V
connections on all the 24 V power
supplies and earth the 0 V supply
at a single point.
` The connection of the 0 V supply
to the central earth bar or earth
fault monitor must be in accordance with relevant national
regulations (e.g. EN 60204-1,
NFPA 79:17-7, NEC: Article 250).
` Minimum range for cable cross
sections on connection terminals
in mm2, in accordance with EN
61131-2, 07/00:
- Power supply:
1.5 (AWG16) ... 2.5 (AWG12)
- Functional earth:
1.5 (AWG16) ... 2.5 (AWG12)
` Use copper wiring.
NOTICE
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical
details).

The supply for the periphery (input
devices) is galvanically isolated
from the module supply. It is fed
from the module bus to terminals
on the base module (connection
level 2 and 3).
The periphery supply is not
switchable and has no current
limitation.
` Inputs
- Short circuit-proof
- The inputs have input filters.
- The head module signals the
input status to the relevant
controller via the bus system.
Signal detection at the inputs
To guarantee that a signal at an input
(“0” signal or “1” signal) is detected,
it must be present for a certain time
period.
If a signal (“0” signal or “1” signal)
does not exceed the pulse
suppression time, it is ignored. The
pulse suppression time depends on
the standard bus system.
Ensure that a correct contact is
made. A correct contact can no
longer be guaranteed when modules
have been inserted and removed
more than 20 times.
