Dual-zone optically isolated DMX splitter RDM hub for DIN rail installation Sundrax Entertainment

Splitter Duo DIN

Streamline Your Lighting with Precision

Invulnerable to electrical interference, the DIN-rail DMX splitter is mounted on 12 modules in the control cabinet, with optically isolated ports, status indicators, and withstanding voltages up to 305V. The DIN cabinet DMX device, configurable with DIP switches, operates on 9 outputs in Single splitter mode, or on 8 outputs as two separate splitter-boosters in Dual splitter mode.

How DIN rail DMX RDM splitter will improve your setup
  • Will take up little space with full functionality – compact DIN-form-factor ensures dense placement of equipment;
  • Will eliminate the risk of equipment damage: optical isolation DMX on each port will protect connected devices from overvoltages and short circuits. Galvanic isolation DIN DMX prevents failures and flickering, ensuring stable operation of the entire system;
  • High voltage DIN splitter, operating up to 305V, is protected from voltage fluctuations in the power grid, and it also protects actuator devices;
  • The splitter works as a booster, amplifying the signal on each line, which allows ensuring stable operation even with a large number of DMX universes and devices;
  • Isolated DMX DIN module sends and receives RDM commands, which allows obtaining information about the status of devices and their operation. This function can be disabled;
  • No delays – starts up in less than 3 seconds after power is supplied;
  • Fanless design does not require maintenance.

Target Audience
Dual-channel configurable DMX/RDM splitter and Industrial DMX isolator is designed for system integrators, installers, and companies working with stationary installations in the field of stage and event lighting. It is suitable for distributors and resellers focused on industrial clients.

Application Scenarios
The product is intended for installation in automation cabinets. It is suitable for lighting control systems in theaters, street and indoor installations, at music festivals, for lighting control in cultural centers, churches, and studios. Also for placement in protected outdoor cabinets at stadiums and concert venues.

      • Protection and stability of the DMX network – 305V AC DMX industrial splitter prevents equipment failure. Optically isolated DMX ports exclude the spread of parasitic currents and induced interferences. If a problem occurs in one segment of the network, and you have a control and signal amplification unit operating as a cabinet DMX isolator, it does not affect the other connections;
      • Signal amplification and distribution – the splitter works as a compact DIN DMX booster. Each new line receives a copy of the signal from the DMX source, which guarantees stable operation of the entire system and allows efficient signal distribution over long cable runs;
      • Diagnostics and remote control – support for the RDM protocol provides advanced capabilities for remote control and diagnostics, simplifying the setup and maintenance of the DMX system on site;
      • Real-time visual control – intelligent mode indicators DMX display states. For example, in DMX512 mode, green light means the presence of a signal, and red – its absence. Statuses on the RDM bus are also visualized;
      • 36-month warranty and CE, RoHS certificates confirm compliance with international quality and safety standards.
      Housing Features
      1. DIN rail DMX splitter is mounted without drilling. Position the module, press on the housing until it clicks, and it's done. The device is easy to redistribute in the cabinet, and it optimizes space;
      2. IP20 housing protects the splitter from particles sized ≥ 12.5 mm, which is sufficient for use in enclosed cabinets. Professional DIN-rail mount DMX splitter is designed for stationary installations where equipment is in a controlled environment;
      3. Laser engraving on the housing ensures clear marking, does not wear off over time, and simplifies the connection process;
      4. Operating temperatures from -40 to +70 °C (from -40 to +158 °F) and resistance to 95% relative air humidity allow using the industrial panel DMX splitter in environments without dust and condensate, while with a wide temperature range, which expands the usage scenarios;
      5. Fanless design does not allow insects to reach the chips and protects the control board from accidental damage. Passive cooling systems ensure silent operation of the cabinet mounted DMX splitter;
      6. 15EDGVC-3.5-03 terminal blocks allow connecting devices without soldering and provide a connection resistant to vibrations and mechanical loads;
      7. The device supports two operating schemes: as one splitter (1 input, 9 outputs) or as two independent splitters (2 inputs, 8 outputs);
      8. Four DIP switches allow manual control of RDM, DUO/Single, Dedicated/Transparent mode, and Display mode, adapting the splitter to specific tasks.
      Usage Examples
      1. In the County Hall, London lighting project, Opto splitter DMX ensured reliable distribution of the DMX signal and effective lighting management in various zones. RDM support simplified system management and diagnostics, ensuring its high performance.
