Doug Fleenor Designs DMX1REL20A Data Sheet

Single Channel DMX512 Controlled Relay Pack

model: DMX1REL20A

technical data sheet

Doug Fleenor Design makes a series of
Relay Packs that are controlled by
DMX512. This single channel unit,
designed to switch up to a 20 amp line

voltage load, 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.

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). Ideal applications
include fog machines, power to moving light fixtures, motorized disco effects, strobe lights, fans, etc.
