The CLS-EXP-DIMU enables the expansion of the
Crestron iLux™ Integrated Lighting System (CLS-C6
series) and other Crestron lighting dimmers to allow
dimming of both forward and reverse phase type loads.
Supported loads include electronic low-voltage, magnetic
low-voltage, incandescent, neon/cold cathode, or 2-wire
dimmable fluorescent. A single model supports 120, 230,
or 277 Volt loads up to 16 Amps.

The CLS-EXP-DIMU simplifies installation by auto-
detecting the dimmable load type connected to it and
selecting the appropriate dimming mode to control that
load. Reverse phase (trailing edge) dimming supports
incandescent and electronic low-voltage load types, while
forward phase (leading edge) dimming handles magnetic
low-voltage, neon, and other inductive load types.

Any output channel of the iLux system can be used to
control the CLS-EXP-DIMU to dim a fully loaded circuit.
It is also compatible with CLW-Series

in-wall dimmers

and select CLX-Series lighting control modules. The
metal enclosure is designed for mounting to a vertical
surface and can be installed in a space used for
environmental air as defined in NEC Article 300.22(C).
Conduit knockouts are provided on the bottom and lower
sides. All connections are made via screw terminals
behind the front cover.
