Crestron CLX-2DIM8 – 8-Channel Dimmer Module, 2 Feeds, 120V

Product Overview

The Crestron CLX-2DIM8 is an 8-channel forward-phase dimmer module designed for installation in Crestron CAEN or CAEN-MLO automation enclosures. It accepts two 120V single-phase feeds (same or split phase) and provides 8 independently controlled channels rated at 16A / 1,920W per channel, with a 32A / 3,840W module total. It is suited for incandescent, magnetic low-voltage, neon/cold cathode, and 2-wire fluorescent load types in residential and commercial lighting control installations.

Product Description

The CLX-2DIM8 communicates via Cresnet secondary mode, receiving dimming commands from a Crestron control processor. Its forward-phase (leading edge) dimming method is optimized for incandescent and magnetic low-voltage loads. The module occupies one slot in a CAEN or CAEN-MLO enclosure and requires adequate ventilation for heat management, as maximum heat dissipation reaches 176 BTU/hr at full load. UL, CEC Title 24, and FCC certifications support use in regulated commercial and residential projects.

Frequently Asked Questions

Q: Does the CLX-2DIM8 support LED loads?
A: No. The CLX-2DIM8 uses forward-phase (leading edge) dimming, which is not optimized for LED fixtures. For LED-compatible dimming, the CLX-2DIMU8 (universal dimmer) or CLX-2DIMFLV8 (0-10V dimmer) are appropriate alternatives.

Q: How many CAEN enclosure slots does the CLX-2DIM8 require?
A: The CLX-2DIM8 occupies one module slot in a standard Crestron CAEN or CAEN-MLO enclosure.

Q: Can the CLX-2DIM8 use two separate 120V circuit feeds?
A: Yes. The CLX-2DIM8 accepts two single-phase 120V feeds, which can be from the same phase or split phases, providing up to 32A total capacity across the two feeds.
