Dimming Module: Line Voltage, 2-Wire/3-Wire

Part Number: DIM1

Line Voltage/3-Wire Dimming Modules are software configurable for either forward or reverse phase control. This provides the ultimate in flexibility for specification and installation.


  • Dimming modules communicate with the lighting control system to report:
    The dimmer’s current dimming level (0-100% on)
    The line source state (available or off)
    The communication status (active / not available)
    The module’s “health” (if the module is defective)
  • These dimmers utilize a relay ahead of the dimmer for complete disconnection from the source voltage when the dimmer is off.
  • Dimming Modules are completely compatible with 3-wire fluorescent dimming ballasts (Hot, Dimmed Hot and Neutral).
  • Dimming Modules allow for a fine granular control down to 1% (or as limited by the dimming ballast specifications when utilized in a 3-wire dimming application).
  • Dimming Modules are compatible with and auto-sensing for line voltages of either 120 VAC or 277 VAC.
  • Dimming Modules are interchangeable with all other RD style relay and dimming modules, providing a higher level of flexibility than currently available in the market.
  • These modules are not suitable for magnetic loads. Use DIM1M for magnetic loads.
