Crestron part number CLXI-2DIM8
The Crestron CLXI-2DIM8 is an 8 channel, 230V dimmer module for Crestron lighting systems, made up of two independent 4 channel dimmers with two feeds. It dims incandescent, magnetic low-voltage, neon/cold cathode and dimmable 2-wire fluorescent loads from a single module space in a CAEN or CAENIB enclosure.

About the Crestron CLXI-2DIM8
Each of the eight channels is rated for 2300 Watts, and the module as a whole is rated at 5980 Watts when fed from two separate 16 Amp feeds. Every channel output has an air-gap relay, provided so that individual circuits can be serviced. The dimmers are built with 40 Amp triacs and oversized heat sinks, with split-bobbin transformers and ground-referenced electronics, and zero-crossing detection backed by Crestron firmware minimises lamp flicker.
The module takes a single module space in any CAEN or CAENIB automation enclosure, and Crestron lists the PAC2 and PAC2M as the controllers for CLXI modules. High-voltage wiring terminates on a CLTI-2DIM8 terminal block, sold separately, which allows the wiring to be terminated at any time before the module itself is fitted.
An override feature lets each channel be adjusted to a preset state during setup. If Cresnet communications are disrupted for any reason, a simple contact closure can be used to activate those override presets. When replacing a module, check the loads on each channel against the 2300 Watt channel rating and the 5980 Watt module rating.

Questions about the Crestron CLXI-2DIM8
What is the Crestron CLXI-2DIM8?
It is the international version of Crestron's 8 channel dimmer module with 2 feeds, for 230V lighting. It is made up of two independent 4 channel dimmers in a single module and dims incandescent, magnetic low-voltage, neon/cold cathode and dimmable 2-wire fluorescent loads as part of a Crestron lighting system.
What are the load ratings of the CLXI-2DIM8?
Each channel is rated for 2300 Watts. The module as a whole is rated for 5980 Watts when it is fed from two separate 16 Amp feeds. Every channel output has an air-gap relay, provided so that individual circuits can be serviced.
Where does the CLXI-2DIM8 mount?
It occupies a single module space in any CAEN or CAENIB automation enclosure. High-voltage wiring terminates on a CLTI-2DIM8 terminal block, which is sold separately and lets the wiring be terminated at any time before the module itself is fitted.
What happens if Cresnet communication is lost?
An override feature lets each channel be adjusted to a preset state during setup. If Cresnet communications are disrupted for any reason, a simple contact closure can be used to activate those override presets. Crestron lists the PAC2 and PAC2M as the controllers for CLXI modules.
How does the module keep lamp flicker down?
Crestron uses a zero-crossing detection technique backed by its own firmware to minimise lamp flicker. The CLXI-Series dimmers are also built with 40 Amp triacs, oversized heat sinks, split-bobbin transformers and ground-referenced electronics.
How much is the Crestron CLXI-2DIM8?
Crestron asks its dealers to give the price of the CLXI-2DIM8 directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the CLXI-2DIM8?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CLXI-2DIM8 on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the CLXI-2DIM8 come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CLXI-2DIM8 develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the CLXI-2DIM8 in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the CLXI-2DIM8 without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
