Description
The ekinex®universal interface is a KNX S-mode device
that can be used as input or output. Depending on the
version, the device is provided with:
- inputs to connect to the bus devices with free-potential
contacts or NTC passive temperature sensors;
- output to control low-consumption LEDs.
The device is provided with an integrated bus commu-
nication module and is realized in a compact design for
installation in ush-mounting wall boxes. The device is
powered by the KNX bus line with a SELV voltage 30 Vdc
and does not require auxiliary power. The scanning volta-
ge for the input channels is produced by the device.

KNX bus device for connecting conventional (not KNX) switches,
sensors or NTC temperature sensors (to the inputs) and/or low-
consumption LEDs (to the outputs). It has to be used in KNX
installations for control of homes and buildings.
A couple of input channels can be programmed to carry
out the function of:
• dimming of lighting devices;
• controlling drives for shading devices (such as shut-
ters, blinds, curtains, etc.).
Each output channel of the device can be programmed
as [DO] for:
• controlling low-consumption LEDs to be used as sta-
tus feedback, orientation nightlights, etc.
As an alternative to programming it as [DI], each input
channel of the EK-CG2-TP version can be programmed
as [AI] for:
• measuring of the air mass temperature with a NTC pas-
sive temperature sensor (NTC 10 kΩ at 25 °C) to be
connected to the input with possibility of sending the
value on the bus
• 2 points (ON / OFF) or proportional (PWM or con-
tinuous) room temperature regulation. The device
is provided with 2 conduction modes (heating and
cooling) with switching via bus and 4 operating modes
(comfort, standby, economy and building protection)
with separate setpoints for heating and cooling.
Automatic switching function of the operating mode
depending on presence or opening windows. The re-
gulation may work with a weighted average of the two
temperature values

Warning! In order to supply the KNX bus lines use
only KNX bus power supplies (e.g. ekinex EK-AB1-
TP or EK-AG1-TP). The use of other power supplies
can compromise the communication and damage
the devices connected to the bus.

Switching, display and connection elements
The device is equipped with a programming LED and a
programming pushbutton, a terminal block for connection
of the KNX bus line and screw terminal blocks for connec-
tion of inputs and outputs.
Switching and display elements

Mounting
The device has degree of protection IP20, and is therefo-
re suitable for use in dry interior rooms. The support EK-
SMG-35 allows the mounting on 35 mm rail in boards or ca-
binets for electrical distribution.
a) Insert the mounting support into the appropriate shaped prole of the
interface
c) Once fastened, connect the bus line, the inputs and the outputs
b) Place the support clamping tooth on the top edge of the mounting
rail and rotate device and support towards the guide until it completely
engages
Conguration and commissioning
Conguration and commissioning of the device re-
quire the use of the ETS®(Engineering Tool Software)
program V4 2.0 or later releases. These activities must
be carried out according to the design of the building au-
tomation system done by a qualied planner.
Conguration
For the conguration of the device parameters the corre-
sponding application program or the whole ekinex®pro-
duct database must be loaded in the ETS program. For
detailed information on conguration options, refer to the
application manual of the device available on the website
www.ekinex.com.
Note. The conguration and commissioning of KNX
devices require specialized skills. To acquire these
skills, you should attend the workshops at KNX cer-
tied training centers.

Commissioning
For commissioning the device the following activities are
required:
• make the electrical connections as described above;
• turn on the bus power supply;
• switch the device operation to the programming mode
by pressing the programming pushbutton located on
the front side of the housing. In this mode of operation,
the programming LED is turned on;
• download into the device the physical address and the
conguration with the ETS®program.
At the end of the download the operation of the device
automatically returns to normal mode; in this mode the
programming LED is turned o󰀨. Now the bus device is
programmed and ready for use.
Reset of the device
To reset the device remove the bus connection by ex-
tracting the bus terminal from its seat. Keeping pressed
the programming pushbutton, reinsert the bus terminal in
his seat; the programming LED blinks fast. Release the
programming button and remove the bus terminal again;
the reset was carried out. Now you need to address and
congure again the device via ETS.
Warning! The reset restores the device back to the
state of delivery from the factory. The address and
the value of the parameters set during conguration
will be lost.
