1 Safety instructions
To avoid potential damage, read and follow the following instructions:
Electrical devices may be mounted and connected only by electrically skilled
persons.
Danger of electric shock. During installation and cable routing, comply with the regu-
lations and standards which apply for SELV circuits.
Danger of electric shock. Make sure during the installation that there is always suffi-
cient insulation between the mains voltage and the bus. A minimum distance of at
least 4 mm must be maintained between bus conductors and mains voltage cores.
Danger of electric shock on the installation. Do not connect any external voltage to
the inputs. The device might be damaged, and the SELV potential on the bus line will
no longer be available.
This manual is an integral part of the product, and must remain with the customer.
2 System information
This device is a product of the KNX system and complies with the KNX directives.
Detailed technical knowledge obtained in KNX training courses is a prerequisite to
proper understanding.
The function of this device depends upon the software. Detailed information on load-
able software and attainable functionality as well as the software itself can be ob-
tained from the manufacturer´s product database.
The device can be updated. Firmware can be easily updated with the Jung ETS Ser-
vice App (additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against
manipulation in building automation and can be configured in the ETS project. De-
tailed technical knowledge is required. A device certificate, which is attached to the
device, is required for safe commissioning. During mounting, the device certificate
must be removed from the device and stored securely.
Planning, installation and commissioning of the device are carried out with the aid of
the ETS, version 5.7.7 and higher or 6.1.0.
3 Intended use
– Outputs for polling of conventional, potential-free contacts in KNX systems and
for sending telegrams to the KNX bus for reporting of states, meter levels, op-
eration of loads, etc.
– Outputs for activation of LEDs
– Mounting in appliance box with dimensions according to DIN 49073 in combin-
ation with a suitable cover

– When mounting behind switch inserts and push-button inserts, use an appli-
ance box with sufficient installation depth
4 Product characteristics
Product characteristics
– Depending on the variant, two, four or eight independent channels, which work
as inputs or as outputs, depending on the ETS configuration
– Common reference potential for all channels
– Disabling of individual channels
– Supply via the KNX bus, no additional supply voltage necessary
Outputs
– Connection of LEDs, e.g. LED lamp, 5 V DC, 2.2 mA
– Short-circuit resistant, overload-protected and reverse-polarity protected
– Switching outputs in parallel possible, for loads with higher energy consump-
tion
Inputs
– Connection of potential-free contacts such as push-buttons, switches or Reed
contacts
– Polling with an impulse current avoids contact fouling (image of an oxide layer)
at the connected contacts
– Operating functions: switching, dimming, controlling of Venetian blinds, moods
or room temperature
– Value transmitter for dimming, colour temperature, RGBW, temperature and
brightness values
– Transmission of the current input state after bus voltage failure
– Connection of door or window contacts for the evaluation of the status open,
closed, tilted and grip position
– Connection of Motion detector mini basic, leakage, condensation and temper-
ature sensors (see accessories)
– Pulse counter with main counter and intermediate counter
– Combination of adjacent input channels for connection of push-button, door
contact and window contact
– Logic functions
5 Mounting and electrical connection
Mount device
In secure operation (preconditions):
– Secure commissioning is activated in the ETS.
Push-button interface

82407703 28.09.2023
J0082407703

– Device certificate entered/scanned or added to the ETS project. A high resolu-
tion camera should be used to scan the QR code.
– Document all passwords and keep them safe.
￭ In secure operation: device certificate must be removed from the device and
stored securely.
￭ Mounting in suitable appliance box. Observe cable routing and spacing
Bus connection
￭ Connect bus with a KNX device connection terminal to KNX connection (1)
(see figure 1).

Installation instructions
– To avoid interference from EMC radiation, the cables of the inputs should not
run parallel to cables carrying mains voltage or to load cables.
– The voltage potentials of the connecting cables for the inputs and outputs are
not galvanically isolated from the bus voltage.
The connecting cables actually lengthen the bus cable. The specification for
the bus cable length (max. 1000 m) must be observed.
– Do not connect the com connections of multiple push-button interfaces.
– Use channels 1 and 2 for NTC temperature sensors (see chapter "Accessor-
ies" } Page 10).
– No series resistance required for the connection of LEDs.
For the extension of the enclosed cable set (see figure 2), observe the max-
imum cable length (see chapter "Technical data" } Page 10). The following
applies: the com cable for each cable set may not have a total length beyond
30 m in length.

DANGER!
Danger of electrical shock when mains voltage 230 V or other external voltages are
connected!
Electric shocks can be fatal.
Device may be destroyed.
Only connect potential-free push-buttons, switches or contacts.
￭ Connect push-buttons, switches, contacts, LED or NTC to enclosed connect-
ing cables (4) according to the connection examples; (see figure 3) to
(see figure 7). The connection examples show the use with inputs and outputs.

To increase the output current, outputs can also be switched parallel to each
other with the same parameterization; in the example here, (see figure 7) K1-
K3 are switched in parallel.

6.1 Safe-state mode and master reset
Safe-state mode
The safe-state mode stops the execution of the loaded application program.
Only the system software of the device is still functional. ETS diagnosis func-
tions and programming of the device are possible.
Activating safe-state mode
￭ Switch off the bus voltage or remove the KNX device connection terminal.
￭ Wait approx. 10 seconds.
￭ Press and hold down the programming button.
￭ Switch on the bus voltage or attach the KNX device connection terminal.
￭ Wait until the programming LED flashes slowly.
￭ Release the programming button.
The safe-state mode is activated.
By briefly pressing the programming button again, the programming mode can
also be switched on and off in the safe-state mode as usual. If the program-
ming mode is active, the programming LED stops flashing.
Deactivating safe-state mode
￭ Switch off bus voltage (wait approx. 10 seconds) or carry out ETS program-
ming.
Master reset
The master reset restores the basic device settings (physical address 15.15.255,
firmware remains in place). The device must then be recommissioned with the ETS.
In secure operation: A master reset deactivates device security. The device can then
be recommissioned with the device certificate.
Performing a master reset
Precondition: The safe-state mode is activated.
￭ Press and hold down the programming button for > 5 s.
The programming LED flashes quickly.
￭ Release the programming button.
The device performs a master reset, restarts and is ready for operation again
after approx. 5 s.

Restoring the device to factory settings
The device can be reset to factory settings with the Jung ETS Service App. This
function uses the firmware contained in the device that was active at the time of de-
livery (delivered state). Restoring the factory settings causes the device to lose its
physical address and configuration.
