Operation and installation manual
KNX IO 511 (1O2I)
(Art. # 5232)
Switching actuator with 1 output and 2 binary inputs
KNX IO 511 (1O2I)
Application
The KNX IO 511 (1O2I) is a compact switching actuator with 1
bi-stable output and 2 binary inputs. The actuator provides the
function for universal outputs including scene control, timer,
staircase lighting and heating valves (PWM for thermoelectric
valve drives).
The inputs can be connected to conventional switches with an
external voltage of 12 to 230 V. In ex-factory settings the inputs
are connected internally to the actuator. The actuator combined
with input B1 serves as a latching relay. Input B2 is used for zero
crossing detection.
Two push buttons and three LEDs allow a local operation and a
visualization of the device state.
In addition to the output and input channels the device includes
16 independent functions for logic or timer control.
1. Installation and Connection
The KNX IO 511 (1O2I) is designed for installation on a DIN rail
(35 mm) with a width of 1 unit (18 mm). An installation-friendly
design with pluggable screw terminals helps to reduce the cost
of commissioning. It features the following controls and displays:
This device is powered by the KNX bus. An external power
supply is not necessary.
The device is not working without bus power.
A. KNX Programming mode
The KNX programming mode is activated/deactivated either by
pressing the flushed KNX programming button ❸ or by simulta-
neously pressing the buttons ❼ and ❽.Accessing the pro-
gramming mode via the device front buttons can be enabled /
disabled via the ETS® by changing the value of Prog. mode on
device front.
When the programming mode is active, the programming LED
❷ and LED Ch/M ❺light red.
B. Manual operation and status display
The LED Ch/M ❺lights up or flashes if the device is successful-
ly powered by the KNX bus.
By pressing button A ❼long, the manual operation mode will
be entered for channel (A). This is indicated by cyclic single
flashing of LED Ch/M ❺in orange.
The actuator (channel A) can be switched on with button On ❼
and switched off with button Off ❽. The manual operation mode
can be exit by pressing the buttons (Esc) ❼und ❽simultane-
ously.
The LED A ❹is used to display the status of the channel (A). It
lights when the channel is on and is switched off when the chan-
nel is off.
By pressing button B ❽long, the manual operation mode will
be entered for channel pair B (Ch B In1/In2).This is indicated by
cyclic double flashing of LED Ch/M ❺in orange.
If manual operation of channel pair B is activated, the bus tele-
grams of In1 and In2 can be triggered by button 1 ❼and 2 ❽,
if input channel is configured by ETS.
LED 1 ❹and LED 2 ❻are used to indicate state of selected
channel pair while manual operation. They light green when the
button 1 ❼ or 2 ❽ is pressed.
The manual operation mode can be exit by pressing the buttons
(Esc) ❼und ❽simultaneously.

2. Ex-factory behavior
In ex-factory state, the binary inputs are internally connected to
the actuator channel.
By applying a voltage pulse to binary input B1, the actuator
switches over (toggle function). The device thus behaves like a
latching relay. This presetting enables the replacement of a
conventional impulse switch by the KNX IO 511 without pro-
gramming. For this function, the device must be connected to the
KNX bus voltage. The KNX IO 511 can then be programmed and
integrated into the KNX system.
Binary input B2 is configured as zero crossing detection. If the
input is connected to phase (L), the actuator switches at zero
crossing of the mains voltage. This protects the relay contacts,
especially with capacitive loads (switching power supplies / LED
lights) and increases the life time of the device. If input B2 is not
connected, the actuator switches without taking into account the
zero crossing.

Press the KNX programming button ❸ and keep it
pressed down
Reconnect the KNX Bus connector ❶ of device
Keep the KNX programming button ❸pressed for at
least another 6 seconds
A short flashing of all LEDs (❷❹❺❻) visualizes the
successful reset of the device to factory default settings.

from the product website of the KNX IO 511 (1O2I)
(www.weinzierl.de) or via the KNX online catalogue.
ETS parameter dialog
The following pages and parameters are visible in the ETS.
D. Description:
The first page shows general information about the device.

©2019 WEINZIERL ENGINEERING GmbH Page 3/15
General settings:
Device name (30 Characters)
An arbitrary name can be assigned for the KNX IO 511 (1O2I).
The device name should be meaningful, e.g. „Living Room“. This
helps the clarity of the ETS project.
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

functionality is activated, the associated group objects as well as
the parameter page “Actuator 1: Lock function” are displayed for
further configuration. If the lock has been activated via the group
object "Lock", the received switching telegrams are not execut-
ed.
In addition to the lock object, there is also a priority object, which
can be switched independently of the lock. Thus, it is possible to
set an output state without affecting other functions.

Example of the priority object:
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.
F. Lock function:
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
- Switch on
- Switch of
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
- Switch on
- Switch off
- State before lock
- State without lock
State before lock:
This restores the original state before the lock was activated.
Switching telegrams received during the lock are ignored.
State without lock:
Here the state of the last received switching telegram is restored.
This takes into account the received switching telegrams during
the lock. Thus, when the lock is deactivated, the last received
switching telegram is set.
Function (Universal output)

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.
Note: 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
1: 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 1: 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.

J. 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.
Note: Typical thermal servo 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 defines 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 unchanged 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.

lock is activated, this value can be set with this parameter.
L. Input B1: 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 “Input …”.with the channel number, which is
also used in this manual. The 1st binary input will be described
below, the functioning of the other channel is according to the
1st.
Function
This parameter defines the functionality of the connected con-
tact. The following options are selectable:
- Disabled
- Switching
- Dimming
- Shutter
- Send value
- Scene
- Impulse counter
- Latching relay, toggle INTERNAL*
- Latching relay, on INTERNAL*
- Latching relay, off INTERNAL*
- Zero crossing detection INTERNAL**
*An internal connection from the binary input to the actuator. In
this case there will be no telegram on the bus, instead directly
the actuator is switched on, off or toggled. With this toggle func-
tion it´s possible, to replace a latching relay with the KNX IO 511
(1O2I) and used all existing wiring, without configuring any new
KNX group addresses at the device.
**An internal connection from the binary input to the actuator to
switch the relay in the zero crossing at 100V –230V / 50Hz –
60Hz. This treats the conducts of the relay wit care and thus
increases the lifetime of the relay. In case that the zero crossing
cannot detected identically e.g. the phases is not connected to
the pin, the relay is switched immediately, like the function is not
selected.
ATTENTION: The zero crossing detection must not be used from
several cannels at the same time!

Scene position 1 - 8
For each position, scene 1 –64 can be activated.
If only one scene position is activated, it is sent on short button
press.
If several scene positions are used, the activated positions are
switched through with each short button press.
Reset scene position
The behavior for selection and transmission of the scene posi-
tions can be determined via the parameter "Reset scene posi-
tion":
- Never
Starting with the first scene position, the next scene
position of the list is sent with each short button press,
after the last scene position has been sent, the list
starts again from the beginning.
- After execution
Beginning with the first scene position, each short but-
ton press switches the scene position by one position
within the execution delay, at the end of the execution
delay, the current scene position is sent
- 5 Sec. - 10 Min.
On each button press the configured delay time is
started.
Starting with the first scene position, the next scene
position of the list is sent with each short button press,
after the last scene position has been sent, the list
starts again from the beginning.
After the delay time has expired, the list starts again at
the first scene position on the next short button press.
When the lock function is used, the scene position is always
reset when unlocking.
Condition on long/very long button press
It is also possible to select how a long and very long button
press is to be treated:
- No reaction
- Save last scene
A telegram for "save scene" with the last sent scene is
triggered.
- Send scene
The scene configured in the appearing parameter is
sent.
- Reset position
This function is used to override the behavior as set in
the "Reset scene position" parameter.
The duration of time for detecting a very long button press is
twice the time for detecting a long button press, as it is parame-
terized in the general settings.
U. Input B1: Scaled counter
This counter can be used to count values on input impulses,
where an integer value or a floating-point value can be selected
as a counter variable. With this function, e.g. Electrical energy
can be counted directly and sent to the bus via an object.
Scaling factor (Value per pulse)
Here, a floating-point value is to be entered. It determines the
value by which the counter value is increased per pulse.

Send condition
This parameter can be used to determine how the current coun-
ter value is to be sent:
- On read
No independent sending of the counter value by the
device. To read the counter value, the read-flag of the
group object has to be set.
- On change
An additional parameter is displayed to select the min-
imal delta from the last sent value for sending a new
counter value
- Cyclically
An additional parameter is displayed to configure the
sending frequency of the counter variable.
- On change and cyclically
Both sending conditions are active.
If the counter is locked by the object, also cyclic sending is
stopped.

point type is the same as the counter value.
Behavior on reaching limit value (object)
Here it is possible to determine whether a 0 or a 1 is
sent via the object “Counter threshold –State” when
the limit value is reached.
Behavior on reaching limit value (counter)
In addition to the limit value itself, it is possible to de-
termine the behavior of the counter when the limit val-
ue is reached:
- Counter continue
Counter value continues increasing on ever
pulse
- Counter reset and continue
Counter value is reset to 0 and continues in-
creasing on ever pulse
- Counter stop
Counter value stays on limit value and must
be reset by object
Send on device restart
It can be determined with this parameter whether the counter
value should be sent when the device is restarted.

W. Input B1: Rate of change
This counter is used to connect devices to the bus where the
rate of change is critical within a time interval, e.g. an anemome-
ter.
Scaling factor (Value per delta in base time span)
A floating-point value is to be entered here. It determines the
value by which the counter value is increased on every pulse
Time base
Here the time base of the rate of change can be specified:
- Pulses per second (e.g. [m/s], [km/h])
Value from parameter Scaling factor is multiplied by 1
- Pulses per hour (e.g. [kW])
Value from parameter Scaling factor is multiplied by
3600
Measurement time span
The measurement time span determines how quickly the counter
can react to changes. Therefore, a short sample rate should be
selected for fast processes (e.g. anemometer).
The rate of change is calculated using the 3 parameters men-
tioned above:
The device saves several meter readings per measurement
interval, scales it with the scaling factor * time base and divides it
by the measuring interval.

Limit value
Here you can edit the checked limit value. The data-
point type is the same as rate of change value.
Behavior on exceeding limit value
In addition to the limit value itself, it is possible to de-
termine whether the counter should transmit 0 or 1 via
the object if the limit value is exceeded.
Behavior on going below limit value
Here it is possible to determine whether the counter
should transmit 0 or 1 via the object if the counter vari-
able goes under limit value.
Example: Electricity meter with S0 interface
From the data sheet of the electricity meter it can be seen that
the device delivers 500 pulses per kWh. A device with constant
power of 1kW is connected to this current meter for one hour.
The scaled counter measures the energy consumed:
Scaling factor: 1 / 500 = 0.002 -> Output in
kWh
The counter for the rate of change measures the current power:
Scaling factor:
- Output in kW: 1/500 = 0.002
- Output in W: 1/500 * 1000 = 2
Time base: Pulses per hour
Measurement time span: 300 s
Example: Anemometer
From the data sheet of the electricity meter it can be seen that
the device delivers 4 pulses/s at a wind speed of 1 m/s.
The counter for the rate of change measures the wind speed:
Scaling factor:
- Output in m/s: 1/4 = 0.25
- Output in km/h: 1/4 * 3.6 = 0.9
Time base: Pulses per second
Measurement time span: 10 s
