The CLS-EXP-DIM enables the expansion of Crestron iLux® Integrated Lighting System (CLS-C6 series) and other Crestron® lighting dimmers to support 120, 230, or 277 Volt loads up to 16 Amps. It allows any output channel of the iLux system to dim a fully loaded circuit of LED, incandescent, magnetic low-voltage, neon/cold cathode, or 2-wire dimmable fluorescent lighting loads. It is also compatible with CLW-Series in-wall dimmers and select CLX-Series lighting control modules.

The CLS-EXP-DIM is designed for mounting to a vertical surface[4], and can be installed in an environmental air-handling space above a suspended ceiling. Conduit knockouts are provided on the bottom and lower sides. All connections are made via screw terminals behind the front cover.
