ABB KNX Tenton SB/U Control Element: 8/12-fold Push-button Interface without LCD
Part of the elegant Tenton design range, the SB/U series provides control over switching, dimming, blind/shutter operation, and scene recall without an LCD screen. It relies on clear, programmable status LEDs and the innovative colour concept (e.g., yellow=lighting, blue=blind) for clear user feedback, making it ideal for robust, low-complexity applications where a display is unnecessary.
The SB/U Control Element is a versatile and cost-effective component for comprehensive lighting and shading management in commercial and residential KNX installations.
1. ABB KNX Tenton SB/U Control Element: Key Functions and Design Simplicity
This series provides high button density for versatile control in a simple, non-LCD form factor.
Control and Functionality:
- Interface: Available as 8-fold (SB/U8) and 12-fold (SB/U12) freely configurable control elements.
- Core Functions: Supports standard KNX controls including switching, dimming, blind/shutter operation, sending values, and scene recall.
- Design Focus: Pure push-button interface; dedicated solely to command transmission and status display via LED (no room temperature controller function).
Design and Feedback:
- Interface Type: Robust physical push-button interface; does not include an LCD display.
- Design Line: Part of the distinct Tenton design range.
- Visual Feedback: Relies on the innovative colour concept via multi-color status LEDs for unambiguous functional identification.
- Installation: Typically supports both Flush Mounted and Surface Mounted installation (for Tenton series consistency).
2. System Integration and Benefits
The SB/U series offers highly reliable and low-complexity integration into the KNX backbone.
- Integration: Used to directly control various actuators, such as a KNX Switch/Dimmer Actuator for lighting and a KNX Shutter Actuator for blinds (Internal Links).
- Benefit: The non-display design provides a **low-maintenance, reliable, and cost-effective** interface solution.
