Installation Sheet
RDD-DM4 4-Channel Integrated Dimmer Module 120,240,277 VAC
The RDD-DM4 Four-Channel Integrated Dimmer Module controls up to six
dimmed channels with four 1200 W onboard dimmers and two satellite
connectors (for RDM series dimmer or switching modules). It is designed
for use with the RDA series of enclosures, in an AMX Lighting™ modular
digital dimming system. The RDD-DM4 is controlled by AXlink, PROlink, or
by dry (contact) closures. The RDD-DM4’s 120, 240, or 277 VAC ratings are
CE, UL, and C-UL approved.
RDD-DM4 UL and C-UL Ratings: (per circuit)
Input
• 120, 240, 277 VAC, single phase, 3-wire, 50/60 Hz, 2400 W, one feed
• 120 ,240, 277 VAC, single phase, 4-wire, 50/60 Hz, 4800 W, dual feed
Output
• 1200 W max. per channel @120, 240, 277 VAC
• 2400 W max. total, all four channels on with 2400 W feed
• 4800 W max. total, all four channels on with dual 2400 W feeds
• Feed circuit #1 goes to dimmer 1 and 3; feed circuit #2 goes to dimmer
2 and 4.

Button/Jumper Information:
• RESET button: By pressing the RESET button, located on the
RDD-DM4 circuit board, it is possible to restart the processor without
having to power-down the unit or disconnect AXlink or PROlink.
RESET does not affect any saved presets or curve settings.
• MEMORY PROTECT on/off jumper: The MEMORY PROTECT
jumper is set to Off by default. When put in the On position, saved
curve settings and presets are protected in case of a power failure.
Caution: Pre-Installation Notes
• All Class 1 wiring must be connected to proper terminals.
• All control wiring must be connected to proper terminals.
• Disconnect power while installing or connecting the unit.
• Keep top and bottom air vents clear at all times.
• Test loads for shorts before connecting.
• Use low-voltage wires with a 300 volt rating or greater.
• Use field-installed copper conductors.
• All electrical ratings are for continuous duty.
• For indoor use only.
• AC lighting loads only.
• This module may require extra power from the AXlink connection or an
external power supply connected to the control card.
Connecting the RDD-DM4 to the AMX Lighting Master
Connecting AXlink:
Connect the 4-pin captive-wire AXlink from the RDD-DM4 to the Central
Controller for AXlink control of the dimming system.
Connecting PROlink:
Connect the orange 4-pin captive-wire PROlink connector from the
RDD-DM4 to a PRO-DP8 PROlink wall panel.
