• Outputs (Ausgänge / sorties / uscite): 2 – one per channel, allowing separate control of two distinct circuits.
• Bus System Compatibility: KNX – the device is fully integrated into the KNX home automation network.
• Powerbus Support: None – the TXA022 operates solely on the KNX bus and does not require a separate powerbus connection.
• IP Rating: IP20 – suitable for indoor use where protection against solid objects larger than 12 mm is required.
• Operating Hours Reserve (Réserve de marche): 25,950 hours – ensuring long‑term reliability and minimal maintenance.

Programming Flexibility

The TXA022 offers a comprehensive daily and weekly program, allowing up to 56 switching actions per channel. This means you can schedule multiple on/off events throughout the day, repeat them weekly, or create unique patterns for each weekday. The device’s programming interface is intuitive, supporting both manual configuration via a keypad and remote configuration through the KNX network.

Installation and Integration

Designed for seamless integration into existing KNX installations, the TXA022 can be mounted in standard DIN rail enclosures or wall boxes. Its compact size and straightforward wiring make it ideal for retrofitting older buildings or incorporating into new smart‑home designs.

Wiring Overview

• Power Supply: Connect to the KNX bus power line (typically 12 V DC).
• Channel 1 Output: Wire to the first load or circuit you wish to control.
• Channel 2 Output: Wire to a second independent load.

Use Cases and Applications
