Lighting DMX switchpack EUROLITE ERX-4 4-channel 16A

EUROLITE ERX-4 4-channel 16A is a DMX switchpack that converts DMX control signals into four independently switched mains outputs. Each output channel supports up to 16 A, enabling centralised on/off control of lights or effects from a DMX controller. The unit is designed to integrate DMX-controlled switching into stage, club and event power distribution, reducing the need for manual switching at fixtures and simplifying cabling layouts.

Advantages

The switchpack offers four isolated switching channels with 16 A capacity each, providing dependable power handling for individual circuits. Its DMX compatibility allows channel-wise remote switching from standard DMX consoles; the compact rack-friendly form factor supports neat installation in technical areas. The device reduces the number of required power runs and allows consolidation of control and power distribution into a single unit for easier system management.

Suitable for

• Stage lighting rigs requiring remote on/off control of multiple fixtures
• Club and bar installations where independent circuit switching is needed
• Event and rental setups that demand fast reconfiguration and central power control
• Integration with DMX lighting desks to drive non-DMX mains loads

Key specifications

• Number of switched channels: 4 independently controllable outputs
• Maximum current per channel: 16 A
• Control protocol: DMX512-compatible control input
• Power connections: mains-rated input and switched outputs suitable for venue wiring
• Form factor: compact housing designed for rack or stage equipment placement

How to use

Connect the ERX-4 mains input to an appropriate supply that matches local electrical standards and ensure proper protective earth connection. Link the DMX feed from the controller to the switchpack’s DMX input using standard DMX cabling and terminate the DMX line as required. Connect each fixture or circuit to the corresponding switched output. Address and configure the unit according to the DMX channel assignments required by your show file or console, then operate channel switching from the DMX controller to toggle mains power to each output.

Usage recommendations

Verify load currents for connected devices to avoid exceeding the 16 A limit per channel; distribute high-draw equipment across multiple channels or use additional switchpacks as needed. Ensure permanent installations follow local electrical codes and are performed by qualified personnel. Use proper DMX cabling and line termination to maintain reliable control signal integrity.
