As part of a complete Crestron lighting system, the CLX-2DIM8 lighting control
module provides 8 channels of dimming for incandescent, magnetic low-voltage,
neon/cold cathode, and dimmable 2-wire fluorescent loads. The CLX-2DIM8 is
actually composed of two independent 4 channel dimmers in a single module. Each
channel is rated for 1920 Watts, with a total module rating of 3840 Watts when fed
from two separate 20 Amp feeds. Air-gap relays are provided on every channel
output allowing individual circuits to be serviced without disabling the
entire module.

CLX-Series dimmers are rigorously built using 40 Amp triacs and oversized heat
sinks for ultimate reliability. Split-bobbin transformers and ground referenced
electronics deliver superior performance. Lamp flicker is minimized through
Crestron’s innovative zero-crossing detection technique backed by proprietary
firmware. Low-maintenance convection cooling assures quiet and
trouble-free operation.

An override feature allows each channel to be adjusted to a preset state during
setup. In the event that Cresnet communications should be disrupted for any
reason, a simple contact closure can be used to activate the override presets on a
global or semi-global basis.

The CLX-2DIM8 occupies a single module space in any CAEN automation
enclosure. Termination of high-voltage wiring to the module is facilitated by a
CLT-2DIM8 terminal block, sold separately to enable termination of the wiring
anytime prior to installing the module. CLX modules are controlled by the PAC2
and PAC2M professional automation control systems via the Cresnet network. A
5-wire link provides bussing of the Cresnet and override signals between modules
within an enclosure (interconnect jumpers included).
