Theben KNX Push-Button Interface Binary Input 4-channel TA 4.1 KNX (4969274)

KNX binary input / push-button interface with 4 potential-free inputs for flush-mounted installation. Enables connection of conventional push-buttons, switches or contacts to the KNX bus, converting them into multifunctional control points for lighting, blinds, scenes and more.

Advantages

Each of the 4 inputs can be independently configured via ETS for switching, dimming, blind control, value transmission (1-byte, 2-byte, scene), counting or sequence control. The compact design fits into standard flush-mounted boxes, and power is supplied directly from the KNX bus, eliminating the need for an additional power supply.

Suitable for

• Integration of existing push-buttons or switches into KNX smart home systems
• Control of lighting, shutters, and scenes from multiple locations
• Retrofit projects where a flush-mounted solution is required
