The Crestron® GL-CAEN-2DIM8 is an eight-channel, two-feed dimmer module designed for 120V commercial lighting system applications. It installs in a CAEN or CAEN-MLO enclosure and provides control of a variety of dimmable lighting load types including incandescent, magnetic low-voltage, neon/cold cathode, and 2-wire fluorescent. Dual feed capability provides two independent four-channel dimmers in one module space. Each output channel is rated for 1920 Watts (16 Amps), with a total module rating of 3840 Watts (32 Amps) when fed from two separate 20 Amp feeds.
Forward Phase Dimming
The GL-CAEN-2DIM8 employs forward phase (leading edge) dimming to handle inductive load types like magnetic low-voltage and neon, as well as incandescent and 2-wire fluorescent.
An air-gap relay on each channel output allows individual circuits to be serviced without disabling the entire module.
Low-maintenance convection cooling with over-sized heatsinks affords silent operation with no mechanical components to wear out.
Emergency Lighting Control
The GL-CAEN-2DIM8 is UL® 924 and CSA® C22.2 No. 141-15 listed for use in controlling emergency lighting loads. In the event of a power failure, a contact closure from a power loss sensor (Crestron GLS-PLS-120/277, sold separately) activates the override mode in the GL-CAEN-2DIM8 to turn on each designated lighting load if it is off (assuming line power is supplied by a backup power source). The override dimming level can be preset to any value when commissioning the lighting system, so even if the load is already on prior to a power failure, it will change to the preset level when override mode is activated.
Centralized Lighting Cabinet Installation
Crestron GL-CAEN series commercial lighting control modules are designed to be installed in a CAEN or CAEN-MLO wall mount enclosure. Available in a variety of sizes, CAEN and CAEN-MLO enclosures provide a scalable, high-density centralized lighting control solution for any-sized commercial building or facility. A selection of GL-CAEN module types is offered to accommodate a wide range of load types and system configurations.
Each lighting control module, including the GL-CAEN-2DIM8, ships complete with a DIN rail terminal block for termination of the high-voltage feed and load wiring. This terminal block mounts beside the module within the enclosure. Low-voltage control signals are bussed between each of the modules within an enclosure via a simple 5-wire link (interconnect jumpers included), which terminates to a single terminal block (model CAEN-BLOCK, sold separately) at the bottom of the enclosure.
The GL-CAEN-2DIM8 interfaces with a Crestron control system (a.k.a., control processor or automation processor) via Cresnet. Cresnet is a simple 4-wire network bus that provides the communications backbone for a system of Crestron lighting dimmers, switches, keypads, shades, thermostats, and other devices.
