Doug Fleenor Design makes a series of Relay Packs that are controlled by DMX512.
The DMX1REL20A is a single channel unit, designed to switch up to a 20 amp line voltage load, and uses a 30 amp relay. The unit is provided with two 18″ 12/3 SJ pigtails for line-in and switched line-out. This version only switches the single ?hot? leg. It is supplied with 15 amp parallel blade connectors as standard, but the unit may be wired with higher rating connectors by special order or may be rewired by the customer. It operates on 100-240V 50/60Hz.
The DMX1REL20A-2POLE is similar to the standard version above, but also includes another 30 amp relay so that both the ?hot? legs are switched. This unit is supplied with 20 amp twist lock connectors (L6-20) and also operates on 208-240V 50/60Hz.
Available connector types: 5 pin XLR, 3 pin XLR, RJ-45 (ESTA or Color Kinetics pinout), or mounted in a JBOX enclosure.
