on the bus. The telegram is received and executed by
one or more KNX actuators. The device is powered by the
KNX bus line with SELV voltage 30 Vdc and requires no
auxiliary power supply. The scanning voltage for the input
connections is produced inside the device.
Main functional characteristics
Each input of the device can be programmed as [DI] to
carry out the function of:
• on/off switching of single loads or group of loads;
• detecting the state of signaling contacts (from safety
devices, alarms, etc.);
• recalling and saving of scenes;
• sending on the bus of values (temperature, brightness,
etc.);
• switching to forced operating mode (lock);
• counting of impulses and switching cycles.
Each pair of inputs can be furthermore programmed for:
• dimming of lighting devices;
• controlling drives for shading devices (such as shutters,
blinds, curtains, etc.).
As an alternative to programming it as [DI], each input 1B,
2B, 3B, 4B 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.
Finally, it is possible to congure up to 4 logic functions
(AND, OR or XOR) with 4 logic objects in input each.

Description
The ekinex®8-fold analog/binary input EK-CA1-TP is a
S-mode KNX modular device for rail mounting for con-
nection to the bus of switches and sensors of conven-
tional type (not communicating natively on the KNX bus)
equipped with potential-free contacts, or NTC passive
temperature sensors. By means of the binary input is pos-
sible to switch and control KNX bus functions with nor-
mal switches, pushbuttons and sensors or binary signals
made available by other devices. In addition, it is possi-
ble to acquire room temperature values, so it can also be
used as a room thermostat for up to 4 independent zones.
The binary input can be used as follows:
- 8 independent inputs for potential-free contacts, for
example for the connection of traditional (not bus)
switches or pushbuttons dedicated to the switching on/
off of loads;
- 4 individually congurable inputs for NTC temperature
sensors;
- 4 independent channels, for example for the connec-
tion of traditional (not bus) pushbuttons for the control
of dimmer or motorized drives.
The device is equipped with an integrated bus communi-
cation module and is designed for rail mounting in distri-
bution boards. To operate the device receives an input
signal and converts it into a corresponding telegram sent

Mounting
The device has degree of protection IP20, and is there-
fore suitable for use in dry interior rooms. The housing is
made for rail mounting according to EN 60715 in boards
or cabinets for electrical distribution. The installation is in
horizontal position, the correct position is when the KNX
bus terminal is located at the bottom and the terminals for
the inputs are located at the top. For the installation of the
device on the rail proceed as follows:
• with the aid of a tool bring the locking device in the fully
lowered position (1);
• place the upper edge of the rear inner prole on the
upper edge of the rail (2);
• rotate the device towards the rail (3);
• push the locking device upward until it stops (4).
Before removing the device, be sure the inputs have been
disconnected and the bus terminal has been extracted
from its slot. Use a screwdriver to slide down the locking
device and remove the device from the rail.
Environmental conditions
• Operating temperature: - 5 ... + 45°C
• Storage temperature: - 25 ... + 55°C
• Transport temperature: - 25 ... + 70°C
• Relative humidity: 95% not condensing
Switching, display and connection elements
The device is equipped with a programming pushbutton
and a programming LED, membrane pushbuttons, LED
for status indication and terminals for connecting the KNX
bus line and the inputs.
Switching elements
• Pushbutton (3) for switching between the normal and
programming operating mode
• Pushbutton (6) for switching between the operating mo-
des: forced (pushbuttons on the front panel: active) or
automatic (pushbuttons on the front panel: not active)
• Pushbuttons (2) for forced operation of the input con-
nections
Switching to the forced operation mode allows to simulate
the state of the inputs with the pushbuttons on the front
panel of the device; in this way it is possible to test the
correct operation of the coordinated loads before connec-
ting any device to the input terminal blocks.
Display elements
• Red LED (4) for displaying the active operating mode of
the device (on = programming, off = normal operation)
• Green LEDs (8) for displaying the switching status of
the input channels (on = closed contact, off = opened
contact)
• Red LED (7) for displaying the operating mode (on =
forced operation, off = automatic operation)
Connection of the KNX bus line
The connection of the KNX bus line is made with the ter-
minal block (black/red) 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 codication: red = + (positive) bus conductor,
black = - (negative) bus conductor

Warning! In order to supply the KNX bus lines use
only a KNX bus power supply (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.
!
Note. In case of failure of bus voltage, the control of
the loads is not possible with the devices connected
to the binary input. It is still possible if the coordina-
ted KNX actuators are equipped with pushbuttons
or other control manual devices and is present the
mains voltage 230 Vac.
i
Note. It is recommended that the installation of the
device always ensure the full accessibility of the
front side to allow the operation of the membrane
pushbuttons.

Connection of the inputs
The connection of the inputs (g. b, c, d) is made with the
screw terminals located at the top.
Conguration and commissioning
Conguration and commissioning of the device require
the use of the ETS®(Engineering Tool Software) program
V4 or later releases. These activities must be carried out
according to the design of the building automation system
done by a qualied planner.
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 off. Now the bus device is
programmed and ready for use.
