RDD-DM6

 6-Channel Integrated Dimmer Module 120,240,277 VAC

The RDD-DM6 Six-Channel Integrated Dimmer Module controls up to six 
dimmed channels with six onboard 10 A dimmers. The RDD-DM6 is 
designed for use with the RDA series of enclosures, in a AMX Lighting™ 
modular digital dimming system. The RDD-DM6 is controlled by AXlink, 
PROlink, or by dry (contact) closures. The RDD-DM6's 120, 240, and 277 
VAC ratings are CE, UL, and C-UL approved.

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.

This module may require extra power from the AXlink connection or an 

external power supply connected to the control card.

Connecting AXlink:

Connect the 4-pin captive-wire AXlink from the RDD-DM6 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-DM6 to a PRO-DP8 PROlink wall panel.

Dual 2400 W Inputs

Bridged 2400 W Input

20 A

Using two feeds for line 1 and line 2 provides
two, 2400 W inputs.

Bridging line 1 and line 2 provides a single
2400 W input.
