Universal interface CG2 (4 IN conf. as DI or NTC / 4 OUT) with thermostat function

DIN-Rail mount modules



The Ekinex® EK-CG2-TP pushbutton interface is a KNX device which can be used as input and/or output module. The device is equipped with 4 configurable inputs and 4 control outputs for low consumption LEDs.

Inputs can be independently configured to connect the KNX bus to:

  • switches, pushbuttons, classic sensors (normally not communicating on the KNX bus ) or any binary signals from other devices, in order to control KNX bus functions;
  • passive temperature sensors (NTC 10 kΩ at 25°C). The environment air mass temperature value, measured by those sensors, can be sent onto the bus or be used to control a room or zone temperature through the integrated thermostat function.

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.

Power supply
  • 30 Vdc power supply by KNX bus
  • Current consumption from bus < 10 mA

Delivery includes a terminal block for connection to the bus. The NTC temperature sensors (page 231) for those channels configured as [AI] must be ordered separately.


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.

Functions / Features
  • Plastic casing

  • Screw terminal blocks for connecting inputs and outputs
  • IP20 protection degree (installed device)
  • Weight 20 g
Configurationa and commissioning

A detailed description of the parameters can be found in the application manual of the device. Configuration and commissioning require ETS5 or later versions. ETS application program: APEKCG2TP##.knxprod (## = release).
