Doug Fleenor Design makes a series of relay packs that are controlled by DMX512. This six channel unit, designed to switch line voltage loads up to 15 amps, uses 30 amp relays. Line voltage input is on an 18" 12/3 SJ pigtail fitted with a 15 amp parallel blade plug (20 amp connector optional). Switched line outputs are on chassis mounted 15 amp parallel blade receptacles.
