2. Description
The KNX B4 Universal Interface is a 4-fold KNX binary input to sensor contacts and
to control/switch/operate KNX devices via classical conventional switches and push
buttons. The input module is suitable to process binary signals of potential-free con-
tacts. Due to its small housing (diagonal of 50 mm) KNX B4 Universal finds enough
room in a flush-mounted box (Ø 60 mm) behind the switch. The connecting cable pairs
of 28 cm can be extended up to 10 m when twisted.
Designed for KNX-enabling of conventional switches and push buttons, KNX B4 Uni-
versal provides a 3.3 V sensing voltage for contact scanning. All usual input functions
like switching, dimming, shutters, blinds control, counter and scenes can be used in a
common way.
Due to its small housing with a diagonal of 50 mm, KNX B4 Universal finds enough
room in a flush-mounted box (Ø 60 mm x 40 mm) behind the switch. The connecting
cable pairs of 28 cm can be extended up to 10 m when twisted.

3. Commissioning
Configuration is made using the KNX software as of ETS 3.0d. The product file can
be downloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de in the “Service” menu. There you will also find the pro-
duct manual.
3.1. Addressing of the device at the bus
The equipment is delivered with the individual address 15.15.255. This can be changed
via the ETS. A button and a control LED are located on the unit for this purpose.
4. Operation
In network installations, KNX B4 Universal can be used as KNX binary input for po-
tential-free contacts. After connecting to KNX TP, KNX B4 Universal operates with its
default settings. Setting the correct Individual Address is necessary to include KNX B4
Universal in the present KNX bus system.

5 Operation
KNX B4 Universal Interface • Version: 13.09.2021 • Technical changes and errors excepted.
4.1. Binary Input Application
KNX B4 Universal provides four binary input channels for contact scanning. They
can be used as single channels and pairwise combined for two-button functions. For
all functions the contact type can be set (NO or NC) and a locking function ("Interlock")
is available. Excluding the counter function also the differing between long and short
button press can throughout be set.
Combining two channels (A/B or C/D) enables the two-button functions "Dimming" and
"Shutter". In single channel mode, following functions can be assigned to a single
channel:
• Switch (toggle, status, short/long)
• Scene (1-bit scene, 8-bit scene with and without long button press saving
function)
• Counter (8-bit, 16-bit, 32-bit)
• Send value: Percent, Angle, Temperature, 2-bit, 8-bit, 16-bit
• One-button dimming
• One-button shutter
To reset an input channel´s counter, a telegram containing "0" or "1" must be received
by the corresponding communication object "Counter reset".
4.2. Programming
4.2.1. Programming of Individual Address and Application
To download Individual Address and/or ETS application the Programming Mode must
be activated. Successive pressing the Programming Button will turn on and off Pro-
gramming Mode. LED C lighting in red colour indicates Programming Mode is active.
To make a download and configure the device, an interface connection (IP, USB) to the
KNX bus system is required. When Programming Mode is activated, the ETS is able to
start the download.
The Individual Address can be assigned to the device by setting the desired address in
the properties window of the ETS. After starting the ETS download and then pressing
the Programming Button the device restarts itself.

6.2.5. One-button dimming
A long button press affects the communication object "Dimming" which is responsible
for the dimming process. A short keystroke button press affects the switching object
"Dimming on/off". Dimming direction is toggled by every button press. The one-button
dimming is a start stop dimming meaning a darker or brighter command is sent until
the button is released. After releasing the button the dimming process stops.

Long button press after 0.3...30.0 s; 2.0 s
Time the input needs to be logical high to start the long operation. If the input is logical
high for a shorter time, only the command for short operation will be sent; available for
"on short/long button press" and "on long button press".
Interlock disabled • enabled
If Interlock is active, changes at the Input are not considered until the Interlock is deacti-
vated again.
Contact type normally open • normally closed
Defines the contact type at the input, NO or NC. If NO is selected, the input is logic high
after the contact is closed.
Long button press after 0.3...30.0 s; 2.0 s
Time the input needs to be logical high to start the long operation. If the input is logical
high for a shorter time, only the command for short operation will be sent.

6.2.6. One-button shutter
A long button press affects the communication object "Sun protection up/down" which
is responsible for starting the up down movement of the shutter or blind. Movement
direction is toggled by every button press. The one-button shutter is a start movement
function meaning a move up or move down command is sent on activation. A short
button press affects the switching object "Blinds open/close" for stopping the
movement and/or adjusting the blinds.
6.3. Channels A/B, C/D
Combined input channels have one two-button function. Configuring the two-button
functions "Dimming" and "Shutter" is only possible by use of combined channels.
According to the setting in the "General" tab either two-button dimming or two-button
shutter can be configured for a combined input. In contrast to the one-button functions,
assignment of buttons can be made individually. For example, it is possible to
configure one button will drive shutters up and the other one will drive them down.
6.3.1. Two-button dimming
Contact type normally open • normally closed
Defines the contact type at the input, NO or NC. If NO is selected, the input is logic high
after the contact is closed.
Long button press after 0.3...30.0 s; 2.0 s
Time the input needs to be logical high to start the long operation. If the input is logical
high for a shorter time, only the command for short operation will be sent.
Interlock disabled • enabled
If Interlock is active, changes at the Input are not considered until the Interlock is deacti-
vated again.
Contact type - Channel A normally open • normally closed
Defines the contact type at the input, NO or NC. If NO is selected, the input is logic high
after the contact is closed.
Contact type - Channel B normally open • normally closed
Defines the contact type at the input, NO or NC. If NO is selected, the input is logic high
after the contact is closed.
Dimming function A/B brighter/darker • darker/brighter
Defines the inputs for dimming up and dimming down.
brighter/darker: • Input A dims up and switches to on.
• Input B dims down and switches to off.
darker/brighter: • Input A dims down and switches to off.
• Input B dims up and switches to on.
Long button press after 0.3...30.0 s; 2.0 s
Time the input needs to be logical high to start the long operation. If the input is logical
high for a shorter time, only the command for short operation will be sent.
