Information
TA 8.1 KNX
8-fold push-button interface, KNX Data Secure, flush-mounted
Art. No.: 4969278
Product description
The Theben TA 8.1 KNX is an advanced 8-fold push-button interface for binary input/binary output, designed for KNX building automation and equipped with KNX Data Secure. Thanks to the ten-wire cable connection with color coding, eight conventional push-buttons or switches can be integrated quickly and securely into any KNX system. The interface supports a wide range of functions such as switching, dimming, blind control, value transmission, sequence activation, temperature measurement and direct LED control.
Applications
- Integration of conventional push-buttons and switches in KNX installations
- Switching and dimming of lighting
- Control of blinds, shutters and sun protection
- Generation of value signals for scenes and logic functions
- Activation of sequences and macros
- Local temperature measurement via optional Theben temperature sensors
- Direct LED control (including low current LEDs) thanks to 3 mA output current
Main features
- 8 independent binary inputs/outputs, fully freely parameterizable
- KNX Data Secure for secure communication
- Ten-wire cable connection with color coding for quick and error-free installation
- Flexible function assignment per channel: switch, push-button, dimmer, blind, value, sequence, temperature sensor, LED control
- 2 switchable inputs for Theben temperature sensors, measuring range -5 °C to +100 °C
- Inputs can be set as outputs, with adjustable blink and pulse function per channel
- Response on bus voltage recovery configurable via ETS
- Flexible installation in standard flush-mounted boxes together with existing switches and push-buttons
- Perfectly suited for retrofit and extension of existing KNX installations
Technical data

- Ambient temperature: -5 °C to +45 °C
- Degree of protection: IP 20
- Protection class: III
- Installation: Flush-mounted in standard box
Important notes
- This device is intended exclusively for use in KNX systems and requires correct KNX configuration via ETS software (with support for KNX Data Secure).
- The TA 8.1 KNX can be combined with conventional push-buttons/switches in standard flush-mounted boxes, enabling simple retrofit without structural work.
- Thanks to the increased output current, many low current LEDs can be controlled directly.
- The color coding of the wire pairs allows easy installation and prevents wiring errors.
- The two switchable inputs are suitable for precise temperature measurement with Theben temperature sensors.
