Imagine being able to control lights, blinds and scenes. Completely wireless, yet with the precision of a true KNX system. The MDT RF-TAL55B202.01S makes exactly that possible: radio technology meets professional KNX integration. Ready for the next level of building automation?

  • KNX RF+ Technology: Operates in System Mode with KNX Data Secure for maximum security and reliability.
  • Flexible Button Assignment: Configure the buttons as pairs or individually – perfect for customised control concepts.
  • Multi-Tap Function: Up to four different values or scenes per button for complex applications.
  • Compatibility with Switch Programmes: Fits common 55 mm frames from GIRA, Jung, Berker, Merten and more.
  • Easy Integration: Connection via MDT KNX RF+ line coupler, ETS programming from version 5.
  • Efficient Radio Range: Up to 150 m in open field thanks to 868.3 MHz transmission.
  • Elegant Design: Pure white glossy for a modern and neutral look.


Why this button can do more than just switch

The MDT RF-TAL55B202.01S is not just a switch. It is a gateway into the world of wireless KNX integration. With its KNX RF+ technology and support for KNX Data Secure, it meets the highest security standards. This means your control commands are not only fast but also encrypted and protected against manipulation.

Installation is simple: you do not need any additional bus cable, just a standard flush-mounted box with 230 V supply. This makes the button ideal for renovations or retrofits in existing buildings where classic KNX bus wiring is not possible.

Furthermore, the configuration options are impressive. Each button can be used as a single or double button. Thanks to the multi-tap function, up to four different values or scenes can be accessed per button. Short or long press? No problem. Two separate communication objects are available. This way you can control lights, blinds, heating values or complex scenes with just one device.

Integration into existing KNX topologies is also straightforward. You connect the button to your installation via an MDT KNX RF+ line coupler. Parameterisation is done as usual via the ETS software (from version 5). There you can not only assign the buttons but also adjust the LED brightness for day and night operation. Four integrated logic blocks allow additional automations directly in the device.

Practical benefits for your smart home

With the RF-TAL55B202.01S you can not only switch or dim lights. It is also suitable for controlling blinds, recalling scenes or sending values such as target temperatures. The multi-tap function opens up completely new possibilities: a short press activates the "Evening light" scene, a long press lowers the blinds, all with the same button.

The radio technology makes the button ideal for retrofits. You don’t have to break open walls to implement KNX. Simply mount, connect to the line coupler, parameterise in ETS – done. This brings professional KNX functionality into existing buildings.

Compatibility with design series

The button fits into almost all common 55 mm switch programmes. Whether GIRA Standard 55, Jung A-Series, Berker S.1 or Merten M-Smart, you can seamlessly integrate the RF-TAL55B202.01S into your existing design. The pure white, glossy finish ensures a modern and neutral look that fits into any environment.

Installation and safety

Installation is carried out in a standard flush-mounted box with a minimum depth of 35 mm. The power supply is provided by the 230 V mains, so no additional wiring is required. Thanks to KNX Data Secure, all telegrams are encrypted, which is an important factor for the security of your building automation.
