ETC Color Source Relay


The Color Source Relay combines power sequencing and data distribution in a portable plug-and-play format.



The Color Source Relay combines power sequencing and data distribution in a portable plug-and-play format. The Color Source Relay comes in wireless- and wired-DMX input. Upon receiving data from the console, its internal sequencing routine automates the process of staggering turn-on times across relays while it provides hardline DMX to connected fixtures.



Applications requiring distributed dimming and position flexibility:

  • Schools
  • Houses of worship
  • Small theaters
  • Event lighting
  • Automated lighting systems
  • Industrial productions
  • Rentals
  • Conference and exhibition centers
  • Multi-use venues such as schools and meeting rooms



  • Input voltage: 90-250V; 47-63Hz
  • Portable two-pole air-gap relay
  • Auto sequencing: turn-on delay in each relay ensures that notwo relays turn on at the same time across a system
  • Data input options (choice per model):
    • Wireless- The relay receives wireless DMX for relayactivation on choice of five wireless IDs selected by thumbwheel and transmits DMX output on hardline connection.
    • DMX (hard wire)- Receives hard wire DMX (input) for relay activation with RDM feedback and configuration while passing through DMX/RDM on the five-pin XLR (output) connector
  • USB master: Connect USB drive for software upgrades
  • Integral Safety Connection
  • Three mounting options: ETC LED yoke (included), universalyoke, or for use on desktop wall-mount




  • CE Compliant; FCC approved
  • RoHS compliant
  • DMX512A compatible
  • RDM compatible (Wired version only)
  • Wireless DMX broadcasts on 2.4GHz range using SpreadSpectrum Frequency Hopping (SSFH)


  • Case manufactured of molded black textured plastic
  • Multiple yoke-fixing hole combinations for flexible mountingto the fixture
  • Convection-cooled; operates without cooling fans
  • Molded safety connection point
  • Power-input and -output connectors arranged at 45-degreeangle to the pipe for ease of tie-off
  • Wireless model includes thumbwheel for selection of sixwireless IDs or custom
  • Wireless model includes 2dBA gain omnidirectional antennae
