LR/S 4.16.1 ABB Light Controller 1-10V 4-Fold Analog Dimming KNX Daylight Harvesting Control Unit

The ABB LR/S 4.16.1 is a high-specification Light Controller 1-10V 4-Fold from the prestigious LR series, engineered to deliver exceptional reliability, precision, and operational efficiency for modern intelligent building environments.

As part of the globally recognized ABB i-bus® KNX ecosystem, this device represents the convergence of advanced engineering standards with high-durability hardware, ensuring seamless coordination of critical building services such as solar shading, lighting control, and system networking.

Designed for professional installation in commercial office towers, luxury hospitality projects, and high-end residential estates, the LR/S 4.16.1 enables building operators to implement modular control architectures that reduce energy overhead while maximizing occupant comfort.

The 4-channel controller powers daylight-harvesting strategies in open offices. Paired with light sensors, it maintains constant lux levels by dimming four lighting zones independently as daylight changes.

• Daylight harvesting in commercial office environments
• Independent control of four lighting zones
• Energy optimization through automated dimming
• Integration with light sensors for constant illumination levels
