1 Application
The KNX IO 510.1 secure (2O) is a compact switching actuator with 2 bi-stable relay outputs.
The outputs are connected as closing contacts.
The actuator provides the function for universal outputs including scene control, timer, staircase
lightning and to control 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 independent functions for logic or timer
control. The device supports KNX Data Security.
2 Installation and connection
The KNX IO 510.1 secure (2O) is designed for a DIN rail (35 mm) with a width of 1 unit (18 mm).
An installation-friendly design with pluggable screw terminals helps to reduce costs of
commissioning. The actuator has the following controls and displays:
❶KNX bus connection
❷Programming LED
❸Button for programming mode
❹LED A On (multicolor)
❺LED Ch/M (multicolor)
❻LED B On (multicolor)
❼Button A On
❽Button B Off
❾Pluggable screw terminals
This device is powered by the KNX bus. An external power supply is not necessary.
If the bus voltage is missing, the device is without function.

2.1 KNX programming mode
The KNX programming mode is activated/deactivated either by pressing the recessed KNX
programming button ❸or by simultaneously pressing the buttons (P/Esc) ❼and ❽.
When the programming mode is active, the programming LED ❷and the LED Mode ❺light up
red.
The operation/visualization of the programming mode on the front can be activated/deactivated in
the ETS® on page general settings.
2.2 Manual operation and status display
The LED Ch/M ❺lights up or flashes if the device is successfully powered by the KNX bus.
By pressing button A On ❼long, the manual operation mode will be entered for the first channel
(A). This is indicated by cyclic single flashing of LED Ch/M ❺in orange.
By pressing button B Off ❽long, the manual operation mode will be entered for the second
channel (B). This is indicated by cyclic double flashing of LED Ch/M ❺in orange.
The respective channel can be switched on with button A On ❼and switched off with button B
Off ❽. The manual operation mode can be exit by pressing the buttons (P/Esc) ❼and ❽
simultaneously.
The LED A On ❹is used to display the status of the first channel (A). It lights when the channel is
on and is switched off when the channel is off. Analogously, the LED B On ❻is used to display
the status of the second channel (B).
Summary of the states of LED Ch/M ❺:
LED Status

LED flashes 1x orange
The programming mode is not active.
Manual operation is active:
Switching first channel (A).
LED flashes 2x orange
The programming mode is not active.
Manual operation is active:
Switching second channel (B).
LED flashes red
The programming mode is not active.
Manual operation is not active.
The device is not loaded correctly
e.g. after aborting a download.

3 Reset to factory default settings
It is possible to reset the device to its factory default settings.
▪Disconnect the KNX bus connector ❶from the device.
▪Press the KNX programming button ❸and keep it pressed down.
▪Reconnect the KNX bus connector ❶to the 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.
In the factory default settings, the device has the physical address 15.15.255 and no group
addresses are connected. Also, KNX Data Security is disabled and the initial key (FDSK) must be
used for secure commissioning.
4 Wiring scheme
4.1 Pluggable screw terminals
The pluggable screw terminals ❾on the left/middle terminal pins Ch A / B Out are used as closer.
On the right terminal pins Ch A / B In the common pins are contacted e.g. the voltage to be
switched. Channel A is located on the upper and channel B on the lower terminal.
It is allowed to connect on the upper terminal compared to the lower terminal a different
phase or voltage.

5 KNX Security
The KNX standard was extended by KNX Security to protect KNX installations from unauthorized
access. KNX Security reliably prevents the monitoring of communication as well as the
manipulation of the system.
The specification for KNX Security distinguishes between KNX IP Security and KNX Data Security.
KNX IP Security protects the communication over IP while on KNX TP the communication remains
unencrypted. Thus, KNX IP Security can also be used in existing KNX systems and with non-
secure KNX TP devices.
KNX Data Security describes the encryption on telegram level. This means that the telegrams on
the twisted pair bus or via RF (radio frequency) are also encrypted.
Encrypted telegrams are longer than the previously used unencrypted ones. For secure
programming via the bus, it is therefore necessary that the interface used (e.g. USB)
and any intermediate line couplers support the so called KNX long frames.

6 ETS database
The ETS5 database (for ETS 5.7 or newer) can be downloaded from the product website of the
KNX IO 510.1 secure (2O) (www.weinzierl.de) or from the ETS online catalogue.
The KNX IO 510.1 secure (2O) supports KNX Data Security to protect the device against
unauthorized access from the KNX bus. If the device is programmed via the KNX bus, this is done
with encrypted telegrams.
6.1 Secure commissioning
If the first product is inserted into a project with KNX Security, the ETS prompts you to enter a
project password.
This password protects the ETS project from unauthorized access. This password is not a key that
is used for KNX communication. The entry of the password can be bypassed with “Cancel”, but this
is not recommended for security reasons.
ETS requires a device certificate for each device with KNX Security that is created in the ETS. This
certificate contains the serial number of the device as well as an initial key (FDSK = Factory
Default Setup Key).
© 2022 WEINZIERL ENGINEERING GmbH Seite 9/30
The certificate is printed as text on the device. It can also be scanned from the printed QR code via
a webcam.
The list of all device certificates can be managed in the ETS panel Reports –Project Security.
This initial key is required to safely put a device into operation from the start. Even if the ETS
download is recorded by a third party, the third party has no access to the secured devices
afterwards. During the first secure download, the initial key is replaced by the ETS with a new key
that is generated individually for each device. This prevents persons or devices who may know the
initial key from accessing the device. The initial key is reactivated after a reset to factory default
settings.
The serial number in the certificate enables the ETS to assign the correct key to a device during a
download.

In the ETS project in the properties of the device, secure commissioning can be activated and the
device certificate can be added:
6.2 Secure group communication
Each object of the device can communicate either encrypted or unencrypted. The encryption is set
under “Security”in the properties of the used group address:
