Product description

The LumenRadio W-DALI Node module is an innovative solution at the forefront of modern lighting control. It enables IEC 62386 without the constraints of physical cabling, providing wireless control of DALI-2 compatible luminaires and devices.

Harnessing the robust capabilities of LumenRadio's MiraMesh technology, the W-DALI Node module ensures reliable radio communication through its self-forming and self-healing wireless mesh architecture. MiraMesh is already trusted by numerous installations worldwide, spanning from lighting control to industrial sensor networks and building automation.

Operating within the internationally approved ISM band at 2.4GHz, the W-DALI Node module offers an operational range of up to 500 meters in line-of-sight conditions. This extensive reach, coupled with its scalable network architecture, allows for flexible deployment scenarios, catering to diverse installation needs.

At its essence, the W-DALI Node module prioritizes seamless integration and compatibility. A W-DALI network consist of a root gateway such as LumenRadio W-DALI DIN Rail and a number of W-DALI Node modules. The gateway communicates over traditional DALI-2 with a controller, and the Node modules in turn do the same with the luminaire or other device in which it is integrated. This "wireless cable" approach allows it to seamlessly integrate into existing wired systems. Additionally, each node supports up to 10 wired devices on its local bus, meaning that a luminaire with an integrated W-DALI Node can act as a bridge to the gateway for a local traditional DALI-2 bus.

The W-DALI Node module requires very limited external circuitry for integration, meaning that it can easily be integrated into a DALI-2 compatible device.
