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‡, 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.

* CLW-Series device must have a dedicated neutral.

† Compatible only with forward-phase dimming modules.

‡ Must be oriented upright, mounted to a vertical surface, with 6 inches (15 cm) minimum spacing above and below for proper ventilation and heat dissipation.

§ Captive screw terminals accept up to two 22 to 12 AWG (0.34 to 4.0 mm2) wires per terminal.
