Please contact us so we can help you custom configure this product.
Overview
The RA122 supports DMX-512 control, architectural remote stations, and contact closure operation for flexible system integration across installed lighting environments. Integrated scene memory allows lighting presets to be stored and recalled without requiring a dedicated lighting console, making the system well suited for both everyday architectural operation and performance-based applications.
Designed as part of the Lightronics Unity Architectural Lighting platform, the RA122-DP communicates with compatible remote stations over the Lightronics Unity Architectural System (LitNet) using an RS-485 architectural control bus. This allows lighting control access from multiple locations throughout a facility while supporting scheduled operation, backup scene playback, and simplified day-to-day lighting management.
Each channel provides 2400 watts of forward-phase dimming capacity and is protected by fast-acting magnetic circuit breakers for dependable long-term operation. Designed for use with incandescent and compatible dimmable fixture types, the RA122-DP operates on 120/208VAC three-phase or 120/240VAC single-phase power systems with 120A per leg. Its rack-mount construction, architectural integration capabilities, and high-capacity dimming performance make it a reliable solution for demanding permanent installation environments.
