ABB LR/S 2.16.1 atuador de regulação universal KNX, 2 canais, calha DIN

The ABB LR/S 2.16.1 is a KNX universal dimming actuator designed for switching and dimming lighting loads in KNX building automation systems. With two independent channels, it supports leading edge and trailing edge dimming, making it compatible with a wide range of lamp types including incandescent, halogen, dimmable LEDs, and dimmable CFLs. The device mounts on a standard DIN rail and occupies 4 TE (module widths). It features manual operation, scene control, staircase lighting function, and status feedback. Protection against short-circuit, overload, and over-temperature ensures reliable operation.

Advantages

Universal dimming principle (leading/trailing edge) ensures compatibility with diverse lamp technologies. Compact 4 TE design saves space in distribution boards. Integrated manual operation allows testing and commissioning without bus connection. Scene control and staircase lighting enhance user comfort and energy efficiency.
