Description
The ekinex®universal interface is a KNX S-mode device
that can be used as input or output. The device includes:
• 4-channels input to connect to the bus devices with
free-potential contacts; one of them can be congured
as NTC passive temperature sensor, along with speci-
c thermostat function;
• 2-channels output with 5 A latching relais.
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. It is powered by
the KNX bus line with a SELV voltage 30 Vdc and does
not require auxiliary power.
The scanning voltage for the input channels is produced
by the device.

Code: EK-CE2-TP
KNX bus device for connecting potential-free contacts
devices as inputs (one of which congurable as passi-
ve NTC temperature sensors or thermostat function) and
2-channels outputs with 5 A bistable relais. It has to be
used in KNX installations for control of homes and buil-
dings.
• counting of impulses and switching cycles;
• save / recall functions for scenes and sequences.
The rst input channel can be programmed to carry out
the following functions alternatively:
• Temperature sensor for values sending;
• on/o type thermostat, to manage control valves for he-
ating/cooling systems or fan coil.
Each output channel of the device can be programmed
as [DO] for:
• single: delay for on and o switching, staircase lighting
function, scene and sequence management, lock and
logic functions;
• coupled: roller shutters or venetian blinds control.

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
• pushbutton (3) for switching between the normal and
programming operating modes
• red LED (2) for indication of the active operating mode
(on = programming, o = normal operation)
Connection elements
• KNX bus terminal block (1)
• 6-pole (4) and 3-pole (5) screw terminals for connec-
tion of inputs and outputs
Connection of the KNX bus line
The connection of the bus line is made with the KNX ter-
minal block (1) included in delivery and inserted into the
slot of the housing.
Characteristics of the KNX terminal block
• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire
conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm
• color codication: red = + (positive) bus conductor,
black = – (negative) bus conductor
Connection of inputs
Inputs are connected by means of the 6-poles screw ter-
minal block (4), inserted into the proper slot of the hou-
sing.
Characteristics of the terminals
• screw clamping of conductors
• maximum cross section of conductor 1 mm²
• recommended wire stripping approx. 5 mm
• torque max 0.2 Nm
In case of input connections longer than 1 m,
shielded cables must be used. In any case, do not
exceed 5 m in length.
Warning! If congured as analogic, to an input
channel it is allowed exclusively the connection of a
NTC temperature sensor with a characteristic resi-
stance value of 10 kΩ at 25°C, β = 3435.
!
Connection of outputs
Outputs are connected by means of the screw terminal
blocks (4), inserted into the specic slots of the housing.
Characteristics of the terminals
• screw clamping of conductors
• maximum cross section of conductor 1 mm²
• recommended wire stripping approx. 5 mm
• torque max 0.2 Nm

Warning! The electrical connection of the device
can be carried out only by qualied personnel. The
incorrect installation may result in electric shock or
re. Before making the electrical connections, make
sure the power supply has been turned o.
!
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 prole 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
Conguration and commissioning
Conguration 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 qualied planner.
Conguration
For the conguration 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 conguration options, refer to the
application manual of the device available on the website
www.ekinex.com.
Note. The conguration and commissioning of KNX
devices require specialized skills. To acquire these
skills, you should attend the workshops at KNX cer-
tied 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
conguration 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
congure 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 conguration
will be lost.
