Splitter Duo Board

Splitter Duo Board – Frameless PCB DMX Splitter for Embedding

Name: Splitter Duo Board
Brand: Sundrax

PCB dual-zone optically isolated DMX splitter RDM hub

The Splitter Duo Board is a frameless DMX splitter on a PCB designed for concealed integration into housings and equipment for OEM applications. It features DIP switches for configuration, AC/DC power options, and galvanic isolation. Configurations are available with 1–3 inputs and 2/4/5 outputs, supporting DMX512 with RDM.

Problems solved by Splitter Duo Board

Need for concealed integration into equipment: the enclosureless PCB DMX splitter can be easily mounted into niches, lamp posts, and custom housings.
Interference and ground loops in metal structures: built-in galvanic isolation on all ports protects the signal from interference and potential damage.
Different power sources: the device can operate on either DC or AC power depending on the chosen model:
- 9–36 V DC DMX splitter (product code SPBD-2D4D-DC)
- 110–220 V AC DMX board (product code SPBD-2D4D-AC)
External cooling requirements affecting niche or housing design: the hidden manhole DMX Splitter Duo Board uses passive cooling and requires no fans even under full load.
Splitting multiple DMX lines: the device can be configured as two independent splitters in Duo mode.
Fast configuration requirements: DIP-switch configuration allows quick and easy on-site setup.

Target audience

This integrator DMX board is designed for system integrators, OEM manufacturers, and distributors creating custom solutions. The device makes it possible to embed professional DMX functionality into any project. It is ideally suited for white-label solutions and for applications requiring custom housing DMX embedding, such as installation in architectural structures or non-standard enclosures. It is also an excellent choice for integration into theatrical scenery and stage props.

- Board-level galvanic isolation: protects each line from electrical interference and ensures operation at voltages up to 305 V.
- DIP-switch configuration: enables on-site setup without software.
- Passive cooling: simplifies enclosure requirements (no forced-air required).
- Protocol compatibility: full support for DMX512 and RDM (ANSI E1.20) ensures intelligent monitoring and diagnostics.
Scenarios of application

This powerful embedded DMX board is intended for concealed installation in professional environments where DMX lines need to be expanded to connect more fixtures. Its compact design enables concealed DMX installation in theaters, cultural centers, arenas, and stadiums. The splitter board can be adapted to exclusive requirements using the provided dimensions and data to build custom housings, including 3D-printed enclosures. The absence of a native enclosure makes it ideal for lamp post DMX installations, where space is limited.

Operating environment

This low-profile DMX board is designed for integration into third-party housings and equipment. Its resistance to external conditions depends on the enclosure in which it is installed. The board itself operates within a temperature range of 0°C to +60°C (32°F to 140°F) and can withstand relative humidity up to 95% (non-condensing).
Installation note
- Install the PCB DMX splitter inside housings with ratings suitable for the intended operating environment.
- In high-humidity conditions, apply a moisture-protective coating to the PCB.
- Verify DC polarity and correct AC wiring before powering the board.
- Secure the board using three screws inside the OEM housing.
This is a ready-to-use OEM embedded DMX module.
