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.
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.
