KNX IO 532 (1D1O)
(Art. # 5313)
Combined dimming/switching actuator with 1 LED dimming PWM output and 1 switching output
KNX IO 532 (1D1O)
Application area
The KNX IO 532 (1D1O) is a compact combined dim-
ming/switching actuator with 1 PWM dimming output for LEDs
and 1 bi-stable relay output.
The dimming actuator can be used e.g. for LED panels or
stripes. Besides controlling the dimmer by switching, rel. dim-
ming and dimming value, several optional functions are integrat-
ed, including scenes, automatic, slumber function or staircase
light.
The switching actuator provides the function for universal outputs
including scene control, timer, staircase lighting and heating
valves (PWM for thermoelectric valve drives).
Two push buttons and three LEDs allow a local operation and a
visualization of the device state.
In addition to the output channels the device includes 16 inde-
pendent functions for logic or timer control.
1. Installation and connection
The KNX IO 532 is designed for installation on a DIN rail (35
mm) with a width of 1 units (18 mm). An installation-friendly
design with pluggable screw terminals helps to reduce the cost
of commissioning. It features the following controls and displays:

3. Wiring scheme
Pluggable screw terminals
Channel A is on the upper terminal and channel B on the lower
terminal:
Upper terminal
The upper pluggable screw terminals ❾are used to control e.g.
LED panels or stripes.
The +12/24V connection of the used power supply unit is con-
nected to the right terminal at the upper screw terminals (12..24V
+), at the same time with the anode of the consumer. The ground
connection of the power supply unit is connected to the middle
terminal (12..24V -). The cathode of the consumer is connected
to the left terminal (Ch A Out -).
Lower terminal
The lower pluggable screw terminals ❾are used for the switch-
ing actuator, the left terminal pin Ch B Out is used as closer. The
central terminal pin Ch B !Out serves as opener. On the right
terminal pins Ch B Cm the common pin is contacted e.g. the
voltage to be switched.
4. Operating parameters of dimmer channel
Power dissipation
The dimming of luminaires is not possible without a certain
power loss in the dimmer. This power dissipation leads to a
heating of the device and depends on several factors. In addition
to the output of the connected lamps, the current dimming value
is also taken into account. Thus, the loss with the luminaire
switched off is almost zero except for the leakage current. Even
at 100%, the power loss is relatively low and can be traced back
to the contact resistance of the output.
Between 0 and 100% the switching losses caused by the PWM
are added. Overall, there is a maximum power loss in the upper
dimming range.
The rated power of 144W refers to the maximum permitted
ambient temperature for free installation. If there are other devic-
es next to the dimming actuator that emit heat, the power that
can be connected is reduced. Alternatively, the devices can also
be mounted at a small distance (approx. ½ TE = 9 mm). Suitable
spacers for the top-hat rail are available on the market for this
purpose.
Safety shutdown
The dimming actuator has an electronic fuse for overcurrent and
overtemperature. In both error cases, the output is switched off
and can be switched on again via a command if the error is no
longer present.
In addition, the device is also equipped with fuses against over-
current and overtemperature. This fuse stage protects connected
devices and surrounding materials against severe damage, but
leads to failure of the dimming actuator and can no longer be
reset.
5. ETS database
The ETS database (for ETS 4.2 ETS and 5) can be downloaded
from the product website of the KNX IO 532 (1D1O)
(www.weinzierl.de) or via the KNX online catalogue.
ETS parameter dialog

Send delay after bus power return
A send delay of telegrams after the return of the bus voltage can
be set via this parameter. In this case, telegrams from the device
are sent to the KNX bus in a delayed manner by the set time.
This results in a reduction of the bus load at a bus power return.
Other functions such as receiving telegrams of switching opera-
tions of the actuator are not affected by this parameter.
Prog. mode on device front
In addition to the normal programming button ❸the device
allows activating the programming mode on the device front
without opening the switchboard cover. The programming mode
can be activated and deactivated via pressing simultaneously
both buttons ❼and ❽.
This feature can be enabled and disabled via the parameter
“Prog. mode on device front”. The recessed programming button
❸(next to the Programming LED ❷) is always enabled and
not influenced by this parameter.
Manual operation on device
This parameter is used to configure the manual operation on the
device. The manual operation mode can be disabled or activated
(with or without time limitation). The time limit defines the dura-
tion until the automatic return from the manual operation mode
back into the normal operating mode.
The device is in normal operating mode when the manual control
is not active. In the manual operating mode, received switching
telegrams are ignored. When the manual operation mode is
terminated (after expiry of the time limit or manually), the last
state of the outputs remains, until a new switching telegram is
received again.
The following options are selectable:
Disabled
Enabled with time limit 1 min
Enabled with time limit 10 min
Enabled with time limit 30 min
Enabled without time limit
Heartbeat
Cyclic sending of values to the KNX-Bus, to indicate that the
device is operational. For the Cycle time values between 1 min
and 24h are selectable.
Alarm objects for error conditions
With this parameter, the following objects for the visualization of
error states become visible:
If an error condition is detected, the dimmer output switches off
and an ON telegram is sent via the respective object. The output
is disabled for the duration of the error state, if it is resolved, the
respective object sends an OFF telegram, and the dimmer can
be used normally again.
Overload is triggered from a load of 8A, overtemperature from a
measured temperature of 85°C in the load section. If no value is
received by the load section for longer than 3 seconds, the error
state "No supply voltage" is triggered.
PWM frequency
Here can be switched between 480Hz and 600Hz PWM fre-
quency.
C. Dimmer A: General
Name (30 Characters)
An arbitrary name can be assigned for the channel. However,
this should be clear and meaningful, this makes it easier to work
with the associated group objects, because the given name is
displayed there as a label. If no name is assigned, the group
objects are named „Dimmer A“.

output value changes to 0%, an ON telegram when the
output value changes from 0% to a value greater than
0%. The value object transmits with a time interval of
at least 1 second if the value at the output has
changed by at least 1% or if a dimming process has
been completed.
Cyclic and on change
State objects send cyclically and on value change.

After the delay time has elapsed, the dimmer is dimmed to the
switch-off or orientation light value depending on the parameter
setting.
Reaction on ON telegram
This parameter determines the behavior after switching on the
staircase function via ON telegram on object 11: When "Switch
on" is set, the channel remains switched on after ON telegram
until the follow-up time is started via OFF telegram. In the setting
"Switch to delay time", the channel enters the delay time imme-
diately after the ON telegram.
Delay time retriggerable
If it is set that the delay time is started with ON telegram, this
parameter determines whether only the 1. ON telegram on object
11 starts the delay time, or also any further.
If it is set that the delay time is started with OFF telegram, this
parameter determines whether only the 1. OFF telegram on
object 11 starts the delay time, or also any other if the staircase
function is already in the delay time.

cess of 0-100%.
F. Dimmer A: Dimming curve
This parameter page is used for fine adjustment of the dimmer to
different light sources.
All parameters on this page only affect the PWM value
of the output, not the dimming or output status value.
Dimming curve
Here it can be specified which PWM values are output by the
dimming outputs when the dimming channel has reached a
certain dimming value. The following options are available:
Linear
Logarithmic
User defined
Gamma
Gamma correction according to the formula:
Gamma is adjustable via parameter from 1.00 to 5.00.

©2019 WEINZIERL ENGINEERING GmbH Page 8/16
DALI
Function based on DALI with the formula:
Dimming output at x%
For the "Linear", "Logarithmic" and "User defined" dimming
curves, these values determine the PWM values of a dimming
output at the specified dimming value. Values between the
specified points are calculated and output linearly. As an exam-
ple, a dimming output with dimming curve "Logarithmic" behaves
according to the following graph:
The output values are fixed for the "Linear" and "Logarithmic"
dimming curves, and can be freely configured for the "User-
defined" curves.
If a dimming value of 0% is reached, the channel always
switches off.
Adjustment of channel
The PWM value of the calculated value by the dimming curve is
additionally scaled with this value.

If the lock was activated by object 22, other received telegrams
for dimmer, automatic mode, slumber, scene function and se-
quencer are not executed.
In addition to the lock object, 3 priority objects become visible
when the lock function is activated, with which the dimmer can
be controlled independently of the lock. This makes it possible to
set an initial state without affecting other functions.
Example of the priority objects:
In the case of events in public buildings or in restaurants, the
normal operation can be set into an inoperative state by the lock
group object. Thus it is possible to lock during the lecture or
concert, switches that are accessible to unauthorized persons, in
order to prevent unmeant switching. Nevertheless, the individual
lamps can controlled by use of the priority object without cancel-
ing the lock.
Polarity of object
This parameter defines, if the lock should be activated by receiv-
ing a 1 or by receiving a 0.
The following options are selectable:
Lock active on 1
Lock active on 0
Behavior on start
This parameter configures, which state the output should set, if
the lock activates.
The following options are selectable:
No reaction
Dim to value
A parameter for adjusting the value appears.
This output state can still be changed by the priority object.
Behavior at end
This parameter defines, which state the output should set, if the
lock deactivates.
The following options are selectable:
No reaction
Dim to value
A parameter for adjusting the value appears.
State before lock
This restores the original state before the lock was ac-
tivated. Telegrams received during the lock are ig-
nored.
State without lock
Here the state of the last received telegram is re-
stored. This takes into account the received telegrams
during the lock. Thus, when the lock is deactivated, the
last received telegram is set.

J. Dimmer A: Sequencer
The sequencer can be used to create complex sequence pro-
grams consisting of up to 32 individual steps for the dimmer
channel. The individual steps can be activated under the follow-
ing starting conditions:
At a fixed time of day
After a waiting time from a previous step has elapsed
By on/off telegram
When receiving a parameterized scene number
When a step is activated, a value can be dimmed to or a scene
number can be sent, and a step or a whole sequence of steps
can be repeated cyclically.
The following objects are available for the general control of the
sequencer:

The following parameters determine the general behavior of the
sequencer:
Steps of sequencer
Number of steps (0...32) to be used
Resume sequence after man. operation
An activated sequence can always be interrupted or continued
via object 33 an ON telegram interrupts the sequence, and with
an OFF telegram it is continued.
A sequence is also interrupted after manual operation, i.e. after
commands for dimmer, automatic mode, slumber or scene func-
tion.
In addition, this parameter determines how an interrupted se-
quence can still be continued:
Only by object
The sequence can only be continued by object 33.
After off-time
The sequence is continued after the set off-time.
On next activated step
The sequence is continued with the next activated
step, the next step can be activated by object or time-
controlled.
Off-time
Only visible if the sequence is to be continued after off-time, with
this parameter the off-time can be configured.
Step after man. operation
This step is executed when resuming after manual operation, the
function of the set step is always executed, regardless of its
otherwise set starting conditions.
Polarity of object “Sequence on/off“
This parameter can be used to set the telegram value with which
the sequence can be switched on and off via object 34. If the
sequence is switched off, any further activation of a step is disa-
bled.
Behavior on switching on
Here it is determined how the sequencer behaves when
switched on by object 34:
No reaction
No function is executed, the sequencer waits for steps
to be activated.
Step x
The function of the step is executed (independent of
the other set start conditions of the step), the se-
quence is then continued according to its configuration
from this step onwards.
Switching on also reactivates a sequence interrupted by manual
operation.
Behavior on switching off
Here it is determined how the sequencer behaves when
switched off by object 34:
Complete actual step
If the sequencer is in a dimming process, it is complet-
ed.
Step x
The function of the step is executed (independent of
the other set start conditions of the step).
Stop immediately
If the sequencer is in a dimming process, it is stopped.
Apart from the set behavior when switching off, any further acti-
vation of a step after switching off is disabled until the sequencer
is switched on again by object 34.
Step 1-32:

When a step is activated, its parameters for configuration ap-
pear.
In the text box at the top right with the content "Step x", you can
enter your own name for the step. This designation serves for
better orientation of the user and has no influence on the func-
tion of the step.
Start by time
This parameter is used to configure a temporal start condition of
the step.
Disabled
Start condition not used
Start at a fixed time of day
Here the time of day at which the step should start can
be entered. When using this start condition, the current
time must have been received via the following object:

Direction
GO 5 Time of Day - Set

From KNX
If no valid time was received by object 5, all
start conditions at fixed times of day are not
active.
The time is continuously updated by the de-
vice through its internal timers, but compo-
nent tolerances always result in a deviation
from the actual time. Therefore, the current
time should be sent to the device by a pre-
cise timer at least twice a day in order to
keep the deviation as small as possible.
- Start after last trigger
Here you can specify the time interval to wait after the
previous activation before executing the step. This
start condition is not available for step 1.
Start time
Here either the time day or the waiting time can be specified for
the execution of the current step, if a timed start condition is
used.
Start by ON/OFF telegram
When using this start condition, a separate object is available for
each step:

Action
When the step is activated, the configured function is executed,
the following functions are available for selection:
None
No function is executed, for example this can be used
to implement a switch-on delay for a sequence.
Start loop
The sequence continues from the selected step. Pa-

function is used for the respective step.
Brightness
Parameters for brightness and fade time become visi-
ble. When this step is activated, the dimmer dims from
the current brightness value to the specified brightness
with the parameterized fade time. This time is related
to a complete dimming process of 0-100%.

is restored. This takes into account the received
switching telegrams during the lock. Thus, when the
lock is deactivated, the last received switching tele-
gram is set.
Function (Switch dimmer)
In this operating mode, for example a dimmer power supply is
switched automatically. With a dimming value of 0% the relay
switches off, with a dimming value >0% it switches on. The

Reaction on ‘OFF’ telegram
This parameter can be used to set whether an OFF telegram on
the object of the staircase function should be processed or ig-
nored.
Time for warning before switch off
The time between pre-warning and deactivation is configured, or
the pre-warning is deactivated with this parameter. If the pre-
warning time is longer than the actual follow-up time, no pre-
warning is carried out.
Time of interrupt
The pre-warning is indicated by a brief interruption (switch off ->
switch on). The duration of this interrupt is configured in this
parameter.
LED lamps often have a long follow-up time, in which
the lamp still lights even though it is already switched
off. With such lamps longer interrupt times must be set
to generate a "visible" interruption.
Function (Valve actuator)
The function valve actuator is foreseen to control thermoelectric
valve drives which are used for floor heating but also for radia-
tors. It maps the continuous position (0% - 100%) to an ongoing
On/Off sequence called PWM (pulse width modulation) signal.
If the valve actuator is selected on the parameter page "Actuator
B: General", a group object for the valve actuator appears in-
stead of the normal switching object. This allows the current
PWM at the output to be set via KNX (0% - 100%). An additional
parameter page "Actuator B: Valve actuator" appears for the
configuration of the valve actuator.
The received control value is saved automatically by the device,
to continue faultless after a possible bus power loss.

P. Actuator B: Valve actuator
Cyclic time (PWM)
The cyclic time of the PWM, which is used to control a servo
drive, is configured with this parameter. One cycle involves a
time range in which the output is switched on and one in which
the output is switched off. The cyclic time corresponds to the
period between two rising edges (state change at the output
from OFF to ON). The longer the flow of the heating circuit (tube
/ pipe length), the higher the cyclic time should be set.
Typical thermal servos require several minutes for a
100% valve change.
Maximum control value (PWM)
This parameter can be used to limit the maximum control value.
The control value is expressed in percent and de-fines the period
during which the output is switched on in one cycle.
Example:
Cyclic time = 10 Min.
Maximum control value (PWM) = 80 %
Maximal output state = ON - 8 min / OFF - 2 min
Stuck protection
With the stuck protection, it is intended to prevent the valve from
being damaged by corrosion or calcification, that it can no longer
be moved. In case stuck protection is enabled, this is only trig-
gered if the value is permanently 0 % or 100 %. On every other
control value the servo already moves, so there is no need for a
stuck protection.
Control value 0% Open servo for the set time
Control value 100%Close servo for the set time
In case the valve is not allowed to open, the stuck protection
must be disabled.
Execution time
If the stuck protection is activated, this parameter is used to set
the duration of the state change.
Monitoring interval
If the stuck protection is activated, this parameter sets the moni-
toring interval. If the state of the output remains un-changed for
this time, the lock protection is triggered.
Protection on missing control value
This parameter enables the protection function on missing con-
trol value telegrams. This is necessary in order to prevent un-
wanted and uncontrolled overheating or cooling down of the
room, when the control value is missing.
Protection takes effect, as soon as no telegrams are received
from the controller over a longer period of time. As soon as this
extended telegram pause has occurred, it can be assumed that
the corresponding controller has failed or the connection be-
tween the controller and the valve actuator has been interrupted.
Protection control value (PWM)
If the protection on missing control value is enabled, this pa-
rameter sets a protection control value. This configured PWM
value will set the output, if the protection is active.
As soon as telegrams from the controller are received again, the
protection control value (PWM) is overwritten by the received
value. The protection does not react again, until the waiting time
in the set monitoring interval is exceeded between individual
telegrams.
Monitoring interval
If the protection on missing control value is enabled, this pa-
rameter sets the monitoring interval. If no further telegram is
received by the device during this time, the protection function
takes effect.
Lock function (with valve actuator)
With this parameter the lock function can be disabled or enabled.
If this functionality is activated, the associated group objects as
well as the parameter page “Actuator 1: Lock function” are dis-
played for further configuration. If the lock has been activated via
the group object "Lock", the received switching telegrams are not
executed.
In addition to the lock object, there is also a priority object, which
can be used to set a control value independently of the lock.
Thus, it is possible to set an output PWM without affecting other
functions.

When the lock is ended, the last received value (not priority
object) is represented as PWM at the output.
