8-fold analog/binary input
Product code: EK-CA1-TP
S
TP1
KNX device for connecting of up to 8 conventional (not
KNX) switches, pushbuttons or 4 analog sensors. It has
to be used in KNX installations for control of homes and
buildings.
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 configurable 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

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 configure up to 4 logic functions
(AND, OR or XOR) with 4 logic objects in input each.
