As part of a complete Crestron lighting system, the CLXI-4HSW4 module provides 4 independent channels of switching for high-inrush loads such as motors, HID lighting, and fluorescent ballasts, as well as incandescent, low-voltage, and neon/cold cathode lighting. Each channel is rated for 16 Amps or 1 HP, with a total module rating of 64 Amps when fed from four separate 16 Amp feeds. Air-gap relays are provided on every channel output allowing individual circuits to be serviced without disabling the entire module.

An override feature allows each channel to be set 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 CLXI-4HSW4 occupies a single module space in any CAEN or CAENIB automation enclosure. Termination of high-voltage wiring to the module is facilitated by a CLTI-4HSW4 terminal block, sold separately to enable termination of the wiring anytime prior to installing the module. CLXI 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).
