24‑Channel Triac DMX512 Switch Pack,Zero‑Cross Trigger,9 Built‑In Chases for Stage Lighting

24‑Ch Thyristor DMX Switch Pack,3‑Pin XLR I/O,Zero‑Cross Switching for Venue Installations

This 24 channel triac dmx512 switch pack is 19‑inch rack‑mount AC power‑switching hardware built for live‑stage performances, theatre venues, bars, club installations and mobile event‑rental projects across Europe and North America. Following DMX512/1990 industry standard, this switch‑pack hardware is designed for pure on‑off control of lighting and effect loads, widely deployed for fixed venue installation and touring rental workflows.

Twenty‑four independent output channels are driven by silicon bidirectional triac components with zero‑crossing triggering mechanism. Channel logic follows fixed DMX threshold rules: channel turns OFF receiving values from 0‑126, and switches ON when signal falls within 127‑255 range. Zero‑crossing trigger greatly suppresses switching‑on current surge and electromagnetic noise, extending service life for both internal circuits and downstream connected loads. Every output channel corresponds to one front‑panel LED indicator, allowing technicians to quickly check real‑time on‑off status at a glance.

Nine pre‑installed internal chase programs are embedded inside the hardware. Operators can toggle working modes among auto‑program, single‑program and external DMX control. Under auto‑program and single‑program modes, playback running speed is fully adjustable via front‑panel up‑down buttons. Digital display shows DMX starting address, program index and selected speed level for easy onsite configuration. When running under DMX control mode, users can set starting DMX address within full 1‑512 address range.

Over‑current protection is realized by rapid‑response fuse, which cuts off circuit once abnormal overload appears, preventing damage to unit and connected lighting fixtures. Standard 3‑pin XLR‑DMX input and output connectors support daisy‑chaining multiple switch‑pack units within one lighting rig. Wide‑range AC 88‑256V 50‑60Hz power input adapts to different mains‑grid standards throughout European nations and United States.

Physical dimension measures 482×146×80 mm with net weight of 2.3 kg, compatible with standard 19‑inch rack‑mount cabinets and flight‑cases for rental transport. This device is for indoor‑only application and must be properly earthed during installation. Operators should configure external circuit breaker according to specification and avoid exceeding per‑channel and total rated current load.

Combining triac zero‑crossing switching, built‑in chase sequences and over‑current safeguard, this rack‑mount switch pack delivers stable on‑off power‑switching capability and becomes a practical accessory for small‑and‑medium‑scale entertainment‑lighting projects throughout Europe and North America.
