EUROLITE DMX Split 8X Splitter 3-pin galvanically isolated 19" Rack 1U

The EUROLITE DMX Split 8X Splitter 3-pin galvanically isolated 19" Rack 1U is a rack-mount DMX512 splitter designed to distribute one DMX input signal to eight separate outputs while providing galvanic isolation on each output. Built for installation in a standard 19" rack at 1U height, it helps prevent ground loops and reduces interference between connected lighting devices and control consoles. The unit is intended for professional environments such as live events, theatres, and rental systems where reliable signal distribution and protection are required.

Advantages

This DMX splitter offers eight isolated outputs in a compact 1U rack form factor, allowing multiple DMX lines to run from a single source without signal degradation. Galvanic isolation on each 3-pin output minimizes risks of ground loop interference and potential damage to control equipment. The device simplifies wiring in complex lighting setups and provides a stable DMX distribution solution for medium to large installations.

Suitable for (tasks / use cases)

• Distributing a single DMX512 control signal to multiple lighting fixtures or dimmer packs
• Technical racks for live concerts, theatre productions, and touring rigs
• Rental companies managing varied show configurations where isolation and reliability are needed
• Permanent stage lighting installations in venues requiring a 19" rack-mounted solution

When it may not be suitable

The unit is not a DMX controller or console and does not generate control signals; it only duplicates and isolates an existing DMX512 input. It may be unnecessary for very small setups with only one or two fixtures where a splitter’s features are not required. Additionally, this model uses 3-pin DMX connections; environments that exclusively use 5-pin DMX connectors will need appropriate adapters or a different splitter model.

Key specifications

• Form factor: 19" rack, 1U height
• DMX standard: DMX512 distribution (input to multiple outputs)
• Number of outputs: 8 isolated outputs
• Connector type: 3-pin (3-pol) DMX connections
• Isolation: galvanic isolation on outputs to prevent ground loops
• Intended use: professional lighting signal distribution for live and installed systems

How to use

Mount the unit in a standard 19" rack occupying one rack unit. Connect the DMX512 signal source (console or transmitter) to the input connector, then connect up to eight DMX runs to the isolated 3-pin output connectors to feed fixtures, dimmers or other DMX devices. Ensure proper cable shielding and route power and data cables to minimize interference. If required by your setup, use appropriate termination on the final device in each DMX line according to DMX512 best practices.

What to consider before purchase

• Verify that your lighting equipment uses 3-pin DMX connectors or plan for adapters if using 5-pin devices
• Confirm that a rack-mounted 1U device fits your existing rack space and transport requirements
• Assess whether eight outputs meet current and anticipated future distribution needs
• Ensure compatibility with your DMX control system and grounding practices

Usage recommendations

For reliable operation, use high-quality, shielded DMX cables and avoid running data lines in parallel with mains power where possible. Terminate each DMX line at the final fixture when recommended, and periodically check connections for corrosion or wear in touring environments. When integrating mixed connector types, use industry-standard adapters and test each output before events to confirm proper isolation and signal integrity.
