RDC-DC Control Card
(120, 240, or 277 VAC)
The RDC-DC 6-Channel Control Card module controls up to six dimmable
channels with six satellite connectors (for RDM series dimmer or switching
modules). The RDC-DC is designed for use with the Radia enclosures, in a
modular digital dimming system. It is controlled by AXlink, PROlink, or by
dry contact closures. The module's 120, 240, and 277 VAC rating is CE, UL
and C-UL approved.
RDC-DC UL and C-UL Ratings:
Line Input
• 120 VAC, 2W+G, 1Ø, 50/60 Hz, 50 mA
• 240 VAC, 2W+G, 1Ø, 50/60 Hz, 25 mA
• 277 VAC, 2W+G, 1Ø, 50/60 Hz, 22 mA
Control Input:
• AXlink
• PROlink
• Eight dry closures
Control Output:
• Six control channels
• Max. total current sourcing 300 mA @ 12 VDC
Specifications:
• Dimensions (HW): 10.0" x 2.75" (254.0 mm x 69.85 mm)
• 12 VDC power (optional)
• Torque terminals to 20 in-lbs. (2.3 N/M)
• Max. wire size: 10 AWG (4 mm²)
• Wire stripping length: 0.28" (7 mm)
• Weight: 1.2 lbs. (0.54 kg)
• Control current: 300 mA for six ports
Button/Jumper Information:
• RESET button: By pressing the Reset button, located on the RDC-DC
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. To protect saved curve settings and presets from
accidental recording, put the jumper in the On position.
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 bents 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.
Connecting RDM Series to the AMX Lighting Master
Connecting AXlink
Connect the 4-pin captive-wire AXlink from the RDC-DC to the Central Con-
troller for AXlink control of the dimming system.
Connecting PROlink:
Connect the orange 4-pin captive-wire PROlink connector from the RDC-
DC to a PRO-DP8 PROlink wall panel.
Connecting Dry Closures
Use the 8 (+ common) dry closures with a WPD8 eight-button wall panel.
Each contact closure connection (1 - 8) is pre-programmed with a default
preset. The table below shows the default presets for each contact closure.
