Doug Fleenor Design makes a series of Relay Packs that are controlled by DMX512.
Doug Fleenor Design relay packs use dry contact air-gap relays. These relays have advantages and disadvantages over the solid state relays found in dimmer packs. Solid state relays can be switched on and off rapidly with no wear, but tend to leak current even when in the off position. Air-gap relays do not leak current, but due to their mechanical design have a finite life span. Doug Fleenor Design Relay Packs should be used where a true off condition is required (no voltage, no current). They should not be used in applications where they will be turned on and off rapidly (for example in chase lights).
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. Supplied with 15 amp parallel blade connectors as standard, the unit may be wired with higher rating connectors by special order or may be rewired by the customer.The DMX6REL15A is a 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.
The DMX6REL30A is the same unit as above but with two 18" 12/3 SJ line in pigtails, one for channels 1 through 3, one for channels 4 through 6.
DMX512 control of low voltage switch closure devices (such as slide projectors and fog machines) is made possible with their low voltage DMX Relay Pack m odels.
Low Voltages models are DMX2REL5A (two-channel 5A 30VDC) and DMX6REL1A (six-channel 1A 30VDC).
