GENERAL DESCRIPTION
This protection module fulfills two basic functions. First it
distributes the current of a large (non NEC Class 2) power
source to four NEC CLASS 2 output channels and therefore
allows for a simpler wiring method and easier approval
process of the entire machine. The second function is to
permit only so much current on the outputs that the input
voltage of this unit (which corresponds to the output
voltage of the power supply) does not fall below 21V.
This ensures a safe and an uninterrupted supply voltage for
sensitive equipments, such as PLCs, controls or sensors, when
they are
connected
directly to the
same power
supply as the
PISA module.
Less critical
loads that are
not affected to short voltage interruptions or that could
even be the cause of a fault on the 24V power supply are
connected to one of the four NEC CLASS 2 output channels
of the PISA module.

PISA11.CLASS2
PISA11-Series PROTECTION MODULE 24V, 4 OUTPUTS
1. INTENDED USE
This device is designed for installation in an enclosure and is intended for the general use such as in industrial control,
office, communication, and instrumentation equipment.
Do not use this protection module in equipment, where malfunction may cause severe personal injury or threaten
human life.
This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.
2. PRODUCT DESCRIPTION
This protection module fulfills two basic functions. First it distributes the current of a large power source to four NEC
CLASS 2 output channels and therefore allows for a simpler wiring method and easier approval process of the entire machine.
The second function is to permit only so much current on the outputs that the input voltage of this unit (which
corresponds to the output voltage of the power supply) does not fall below 21V. This ensures a reliable supply voltage
for sensitive equipments, such as PLCs, controls or sensors, when they are connected directly to the same power supply
as the PISA protection module.
The protection module has one 24V input and four output channels to which the current is distributed. Each output
channel is equipped with a redundant over-current protection, which avoids that wires will be overloaded. All four
output channels will shutdown simultaneously, if the current of one individual channel or the maximum allowed
current for the protection module is exceeded.
A safeguard circuit in the input stage of the PISA module works like a valve. It permits only so much current that the
input voltage does not drop below 21V. In case the input voltage would fall below this value (e.g. due to overloads,
too small of a power supply or high inrush currents such as from starting a motor), all four output channels will be
actively current limited and will shutdown after a certain period of time.
A typical wiring configuration is shown below. All sensitive loads are connected directly to the power supply. If
needed, these load circuits can be protected with standard circuit breakers or fuses. Loads which are less sensitive to
voltage dips or interruptions or which are the source
of the voltage drop themselves are connected to the
output of the PISA protection module.

3. INSTALLATION REQUIREMENTS
This protection module is suitable for DIN-rail mounting. Use DIN-Rails according to EN 60715 or EN 50022 with a
height of 7.5 or 15mm.
The protection module can be used with any regulated 24Vdc power supply. If the power source can deliver more than
40A continuous, the PISA module shall be equipped with an external input fuse (e.g. 30/32A). The power capability
and performance of the power supply can limit the output characteristics of the PISA module.
Make sure that the input voltage polarity is correct before applying the input voltage.
Do not connect batteries to the outputs of the PISA11 module.
This device may only be installed and put into operation by qualified personnel.
The unit does not contain serviceable parts.

6. CURRENT LIMITATION AND SHUTDOWN BEHAVIOR
The PISA11 protection module comprises one common limitation and switching element for all four outputs. In a
protection event, all four outputs limit the current or shutdown at the same time.
The following reasons can cause a limitation of the output currents or a shutdown of the output channels:
1) The output current of one or more output channels was too high.
2) The sum of the output current of all four output channels was exceeded.
3) The outputs needed to be shutdown in order to maintain sufficient input voltage.
Shutdown times*) when exceeding the rated output current:
At 2-times the rated current typ. 1s at 7.4A
At short circuit typ. 10ms
*) The timer for shutdown starts immediately once the rated current levels are exceeded. All output channels will shutdown, if one channel
is overloaded. See Fig. 6-1 for more values.
A shutdown of the outputs can also happen earlier, e.g. when the PISA module has to protect the supply voltage in case the power
supply can not deliver enough current to support all loads without going into overload.

PISA11.CLASS2
PISA11-Series PROTECTION MODULE 24V, 4 OUTPUTS
Shutdown behavior to avoid under-voltage situations on the supply voltage
A further limitation of the output current activates when the supplying power source can not deliver enough current
to support all loads without bringing the power source into overload followed by a voltage drop. In such an event, the
voltage dependent current limitation of the input stage of the protection module is activated (safeguard circuit). This
safeguard circuit acts like a valve only permitting so much current so that the supply voltage does not fall below 21V.
The period of time for how long the protection circuit is able to actively limit the current depends on the difference
between input and output voltage and the current which flows through the PISA protection module and is limited to
a maximum of 5s. All four outputs will shutdown simultaneously.
Shutdown times for a short circuit condition across the outputs can be found in Fig. 6-2.

7. CONNECTING CAPACITIVE LOADS TO THE OUTPUTS
Large input capacitors of drives, monitors or other similar loads can result in an unintended shutdown of the module
when trying to turn-on such loads. This especially can occur after a reset or by turning on a load via the push button or
the external signal input. The PISA protection module is designed to be exceptionally compatible with such types of
loads. The module can turn-on as much capacitance as possible and comprises several different protection mechanisms
to protect against an unintended shutdown or damage of the unit.
The permissible capacitor sizes which can be connected to the output of the PISA module depends on the load current
itself as well as on the characteristic of the load.
The following tables show two typical cases (case A and case B) for the permissible capacitors, which can be connected
on the outputs without shutdown of the protection module. The listed values are valid for the entire temperature
range.
Case A: All outputs are loaded.
The minimum values are worst-case figures for the permissible capacitors which are defined with an additional
constant current load and with the maximum permissible total current of the PISA protection module. See also the
parameter list below the table.
The typical values are defined with an additional resistive load. See also the parameter list below the table.

10. SYNCHRONIZATION OF MULTIPLE PISA MODULES
If multiple PISA modules are used on the same power supply, it is recommended to connect the sync. bus of all
modules together. If one unit shuts down due to the protection function of the input voltage protection circuit
(safeguard), all other modules will shutdown too. This avoids a false interpretation of which output channel caused
the problem. If the sync. terminals are not linked, the module with the highest safeguard protection voltage level
(caused by tolerances) would shutdown
first regardless whether the failure was
caused by this module or not.

12. BACK-FEEDING LOADS
Loads such as decelerating motors and inductors can feed voltage back to the PISA11 protection module. This feature
is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).
The protection module is resistant and does not show malfunctioning when a load feeds back voltage up to 30Vdc to
the protection module. It does not matter whether the protection module is on or off.
The protection module has no capability to absorb energy. Internal diodes (integrated body diodes of the Mosfets)
directs the voltage and energy to the power supply, which is connected on the input side of the protection module.
The power supply defines the amount of energy which can be absorbed.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the
capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit
has been running for 50 000h or only for 100h.

15. FRONT SIDE AND USER ELEMENTS
A Output Terminals (plus (+) pole connection points)
B Red Failure LEDs
The red LEDs are failure indicators. Any time a red LED is on or
blinking, the outputs have been shutdown.
Three reasons why the outputs have been shutdown:
1) The output current of one or more individual output channels
was too high. In this case, the affected output channel LED is
blinking and all others are illuminated.
2) The sum of the output current of all four output channels was
exceeded. In this case, all red LEDs are blinking.
3) The outputs needed to be shutdown in order to maintain
sufficient input voltage. In this case, all red LEDs are on and the
green LED (Input Status) is blinking.
The outputs can also be turned off by pushing the ON/OFF button
on the front of the unit or by applying an external signal to the
ON/OFF signal input. In this case, all red LEDs are on.
When LED 1 and 4 as well as the LEDs 2 and 3 are alternately
blinking, an internal error has occurred. Try to reset the unit by
pushing the reset button. If this does not help, ship the unit to the
factory for inspection.
C ON/OFF and Reset Button
This is a pushbutton which can be used for two purposes:
1) In a failure mode (outputs have shutdown), the outputs can be
turned on again by pushing and holding the reset button for
more than 1 second.
2) In normal mode (outputs have not shutdown), a short (> 50ms) push will turn all outputs ON or OFF.
The unit will be shipped (factory setting) with the outputs turned-on. The ON/OFF function has no safety feature
included.
D Synchronization Bus (connection by plug-connector on the front), See also chapter 10.
If multiple PISA modules are used on the same power supply, it is recommended to connect the sync. bus of all
modules together. If one unit shuts down due to the protection function of the input voltage protection circuit, all
other modules will shutdown too. This avoids a false interpretation of which output channel caused the problem.
If the cause for the shutdown was an over-current of one individual channel only this module will shutdown and
the other modules will stay on. In this case the sync. line has no impact on the other modules.
E Output-OK Relay Contact (connection by plug-connector on the front), See also chapter 8.
This relay contact is closed when the input voltage is sufficient and all outputs are not shutdown.
F Inhibit / Reset Signal Input (connection by plug-connector on the front), See also chapter 9.
This signal input is galvanically isolated with an integrated optocoupler and works in the same manner as the reset
and ON/OFF button. The ON/OFF function has no safety feature included.
1) In a failure mode (outputs have shutdown), the outputs can be turned on again by applying a voltage for more
than 1 second.
2) In normal mode (outputs have not shutdown), a short (> 50ms) voltage pulse will turn all outputs ON or OFF.
G Green Input Status LED
This LED indicates the status of the input. The green LED is illuminated if the input voltage is higher than 21Vdc.
The green LED will blink when the input protection circuit (Safeguard) is activated in order to protect the supply
voltage from dropping below 21V or when the outputs have already been shutdown due to a low input voltage.
H Input Terminals
Two minus (-) connection points for simpler load distribution or grounding (earthing) of the minus (-) pole.
Please note:
Outputs which have shutdown must be turned on manually by pushing the reset button or by an external reset signal
(ON/OFF signal input). A cycling of the input power does not reset the unit. The failure signals are stored until a reset
is intentionally initiated.
