Description
The Ekinex® EK-CA1-TP binary input has 8 independent input channels for connecting
to the KNX bus commands and sensors of traditional type, having potential-free
contacts. Thanks to the binary input, it is possible to command and control bus
functions with standard switches, pushbuttons or sensors (not natively communicating
with the KNX bus) or binary signals made available by other devices. The query voltage
of input channels is produced within the device. The device integrates a KNX bus
communication module and is realized for mounting on a standard 35 mm DIN-rail.
The device is supplied by the KNX bus and does not require auxiliary power supply.
Main features
• Plastic casing
• Frontal programming pushbutton and LED

Description
The Ekinex® universal interface is a KNX device which can be used as input and/or
output module. The device is equipped with:
• 2 or 4 inputs to connect the KNX bus to switches, pushbuttons or classic sensors
(normally not communicating on the KNX bus) or any binary signals from other
devices, in order to control KNX bus functions;
• 2 or 4 control outputs for low consumption LEDs.
The voltage for polling the inputs is supplied within the device. The device integrates
a KNX bus communication module and is realized for flush-mounting or for mounting
on a standard 35 mm DIN-rail. The device is powered by the KNX bus and does not
require auxiliary power supply.
Main features
• Plastic casing
• Programming pushbutton and LED on the case
• Connection to bus line with KNX terminal block
• Screw terminal blocks for connecting inputs and outputs
• IP20 protection degree (installed device)
Power supply
• 30 Vdc power supply by KNX bus
• Current consumption from bus < 10 mA
Products included
Delivery includes a terminal block for connection to the bus.
Accessories
Support for mounting on a standard 35 mm DIN-rail (code EK-SMG-35) and spring for
snapping on the back of Ekinex® wall-mount devices (code EK-MAR-...) to be ordered
separately.
