RE-DM4 and RE-DM6 RADIA Eclipse Dimmer Modules
Low-Voltage Connections
The low-voltage area in the AMX Lighting controllers contain connections and DIP switches for
AXLink, dry closures, and module jack connectors. On the controller cards, low-voltage power for the
board is supplied either by line power, optional auxiliary power supply (RDA-PSM), or the +12 VDC pin
on the AXLink connector. The green status LED on the controller circuit board also blinks, according to
the current operating status of AXLink and red LEDs, one for each of the external connectors for
additional modules. FIG. 24 shows an example of the low-voltage connections, DIP switches and LEDs
using the RE-DM4 controller.
Module connections
When connecting a dimming/switching module to a AMX Lighting controller, connect it as shown in
FIG. 25.
All low-voltage connections must comply with Class 2 wiring codes.
