Crestron CLX-2DIMU8 8-Channel Universal Dimmer Module, 2 Feeds, 120V

Product Overview

The Crestron CLX-2DIMU8 is an 8-channel universal dimmer module designed for integration into Crestron lighting control systems. Supporting 120V operation with two independent line feeds, the CLX-2DIMU8 accommodates a wide range of lamp and driver types including incandescent, magnetic low voltage, electronic low voltage, fluorescent, and LED loads. Engineered for commercial and residential applications, the module mounts on a DIN rail or directly to a panel and connects to the Crestron CLX (Crestron Lighting) control bus.

Product Description

The CLX-2DIMU8 provides AV integrators and building automation professionals with a dense, flexible dimming solution in a single module. Eight independent dimmer channels give installers the ability to control multiple zones from one device, reducing rack or panel space while maintaining precise per-channel control. The two separate line feed inputs (Feed A and Feed B) allow circuits from two different branch circuits or breakers to share a single module, an important feature in larger commercial installations where load distribution across panels is required.

Universal dimmer compatibility eliminates the need to stock separate modules for different lamp technologies. A single CLX-2DIMU8 can manage incandescent fixtures, magnetic and electronic low voltage drivers, fluorescent ballasts, and LED drivers simultaneously across its eight channels. This flexibility is particularly valuable in retrofit projects where existing fixture types are mixed or in facilities transitioning to LED where not all zones are converted at the same time.

The module integrates directly with the Crestron CLX system, communicating with the Crestron control processor over the CLX bus. Control programs on the processor manage dimmer levels, scenes, and schedules. Combined with other CLX modules, the CLX-2DIMU8 supports scalable lighting control architectures suitable for conference rooms, offices, auditoriums, and multi-room residential environments.

Frequently Asked Questions

What load types does the CLX-2DIMU8 support?

The CLX-2DIMU8 is a universal dimmer, supporting incandescent, magnetic low voltage (MLV), electronic low voltage (ELV), fluorescent, and LED loads. This allows a single module to manage mixed fixture types across its eight channels.

Can the two line feeds power circuits from different branch circuits?

Yes. Feed A and Feed B are independent line feed inputs, which allows channels assigned to each feed to draw power from separate branch circuits or breakers. This is useful in commercial installations where load balancing across panels is a design requirement.

How does the CLX-2DIMU8 connect to the Crestron control system?

The CLX-2DIMU8 connects to the Crestron CLX bus, which links CLX lighting modules to a Crestron control processor. The processor runs the control program that manages dimmer levels, scenes, and scheduling for all connected CLX modules.

How is the CLX-2DIMU8 mounted?

The module supports DIN rail mounting or direct panel mounting, providing flexibility for installation in standard electrical enclosures and lighting control panels.

How many zones can be controlled with the CLX-2DIMU8?

The CLX-2DIMU8 provides 8 independent dimmer channels, each representing a controllable zone. Additional CLX modules can be added to expand the total zone count within a CLX system installation.
