DR-4SWD16A DIN-rail mountable relay provides 4 channels of independent relay switching signal for 3520W lighting fixtures and 4 channels of 0-10V dimming signal for dimming driver of fluorescent lamps or LEDs.



  • Designed for standard 35mm DIN rail installation [Space Occupation: 4P (per P:18mm)].
  • 4 channels of 16A relay switching signal and 4 channels of 1-10V dimming signal.
  • Configurable initial value of each channel (relay and dimming).
  • Sequential start of each channel to avoid power grid turbulence due to simultaneous startup.
  • Physical control buttons for manual operation in case of networking malfunctions.
  • Local or remote programming and commissioning.
  • ±2 kV ESD protection to protect dimming port from short circuit and overcurrent.
  • 3600 levels of dimming accuracy, 0%-100% dimming. Dimming curves can be set based on lamps to achieve true linear dimming.
  • Online upgrading.
  • Communication through DR-Link interface.
