The RDDALI is a single channel 800W DALI dimming module. The unit is designed to be ceiling mounted locally to the luminaries or non-dimmed load and will fit through a standard down light cut-out. The RDDALI is suitable for DALI Fluorescent luminaries. Its compact design makes it easy to retro-fit, making scene-set installations as simple as possible. Each unit stores, in non-volatile RAM memory, its user definable addresses: up to 256 house and 256 room addresses, accommodating the largest of schemes. The dimming module also stores its own channel addresses (up to 15 per room) and 4 user-programmable scene settings. Communication with other Rako devices such as the RCP keypads is via coded FM radio, totally eliminating the need for control wiring.
