The Doug Fleenor Design 96-Channel DMX Relay Pack is a high-density, professional control interface designed to translate DMX-512 control signals into physical on/off switching for a vast array of non-dimmed electrical devices. It serves as a crucial component in theatrical, architectural, and special effects lighting where precise, reliable control of machinery, solenoids, smoke machines, motorized fixtures, or conventional power outlets is required. The unit receives standard DMX data and, through its internal processing, uses that data to independently open or close up to 96 individual relay circuits. Each relay corresponds to one DMX control channel, allowing a lighting console programmer to create intricate sequences, timed triggers, and complex cueing for non-lighting equipment as seamlessly as they would for intelligent lights, all within the same show file.

Built with the rugged reliability for which Doug Fleenor Design is known, the relay pack is engineered for mission-critical performance in demanding live production environments. The relays are typically industrial-grade, capable of handling significant inductive and resistive loads (such as motors or high-wattage lamps) with appropriate voltage and current ratings. The unit features robust protection against voltage spikes, noise, and incorrect wiring to ensure longevity and safe operation. Setup involves addressing the unit within the DMX universe and configuring the response of each relay (e.g., latching or momentary, normally open or closed) via DIP switches or software, providing great flexibility for different types of controlled devices.

The power of this system lies in its capacity to centralize and automate control over a massive number of discrete events from a single, familiar lighting console. It enables theatrical productions to synchronize practical effects like moving set pieces, triggering pyrotechnic igniters (with proper safety interfaces), or turning on work lights with the lighting cues. In permanent installations, it can manage the sequenced power-up of equipment racks or control decorative lighting elements. By extending the DMX protocol beyond dimming and moving lights to direct mechanical control, the Doug Fleenor 96-Channel Relay Pack becomes an indispensable tool for creating fully integrated, dynamic, and automated physical environments, expanding the creative palette of designers and technical directors.
