D24A 24-Channel DMX512 Decoder with OLED Display | 12–24V CV LED Driver

Overview

The D24A is a professional 24-channel DMX512 decoder featuring high-performance signal processing, an OLED display for easy configuration and flexible PWM output options. Designed for large RGB, RGBW, CCT or complex multi-channel LED installations, the D24A converts DMX512 digital signals into 24 independent constant voltage outputs. With 12–24V DC input, selectable PWM frequencies and advanced addressing modes, it is ideal for architectural lighting, stage installations and commercial LED systems requiring precise and stable multi-channel control.

Key Features

• 24-channel DMX512 decoder for constant voltage LED systems
• OLED screen for clear setup, addressing and status monitoring
• 12–24V DC input, suitable for multi-channel LED strip systems
• 24 outputs × 4A each (up to 96A total)
• Supports DMX512, RDM (depending on model) and advanced addressing modes
• Select from multiple PWM frequencies for flicker-free performance
• 0–100% smooth dimming with high-resolution output
• Multiple dimming curves and output modes
• DMX address selection via OLED screen and onboard buttons
• Memory function preserves settings after power loss
• Short-circuit, overload and thermal protection
• Heavy-duty metal housing for professional installations

Technical Notes

• The 24 channels can be grouped for RGB, RGBW, CCT or custom channel assignments.
• Supports standard DMX512 addressing: start address set via OLED interface.
• PWM frequency options help eliminate flicker in sensitive recording environments.
• High-current output allows long LED strip runs or multiple fixtures per channel.
• Use stable constant voltage drivers (12V or 24V) matched to LED strip requirements.
• Works with DMX controllers, consoles, software interfaces and building automation systems.

Wiring & Installation Notes

• Connect 12–24V DC power to the input terminals (observe polarity).
• Connect LED strips or fixtures to channels CH1–CH24.
• DMX input and DMX loop (thru) use standard DMX512 wiring conventions.
• Use twisted-pair DMX cable for long-distance transmission.
• Terminate last DMX fixture with a 120Ω resistor for best stability.
• Configure DMX start address and channel mode via OLED display.
• Install in a well-ventilated area; avoid enclosed, unventilated spaces.
• Indoor installation only (IP20).

Applications

• RGB, RGBW and multi-channel LED strip systems
• CCT tunable white LED installations
• Large architectural lighting projects
• Stage, event and entertainment lighting
• Commercial and hospitality DMX installations
• LED matrix or pixel-style channel control
• Any project requiring up to 24 independent PWM outputs
