Crestron DIN-1DIMU4 – 4-Channel Universal Dimmer, 1 Feed, DIN Rail Mount

Product Overview

The Crestron DIN-1DIMU4 is a 4-channel universal dimmer module that mounts on a 35 mm DIN rail, designed for integration into Crestron CAEN enclosures or standard DIN rail panels. It accepts a single 120-240 VAC feed and provides 4 independently controlled output channels rated at 5A/600W per channel (at 120VAC). It is controlled via Cresnet secondary mode and is compatible with a wide range of dimmable load types including LED, incandescent, and low-voltage fixtures.

Product Description

The DIN-1DIMU4 operates as a secondary Cresnet device, receiving commands from a Crestron control processor. Its forward and reverse phase dimming modes accommodate incandescent, magnetic and electronic low-voltage, neon/cold cathode, and dimmable 2-wire fluorescent loads. LED compatibility is also supported in mode-dependent configurations. It fits standard 35 mm DIN EN 60715 rails and occupies 12 DIN module spaces (216 mm wide). Adequate ventilation clearance of 4-6 in. is required above and below the unit. UL, CE, CEC Title 24 2013, and FCC certifications are included.

Frequently Asked Questions

Q: Is the DIN-1DIMU4 compatible with all LED drivers and bulbs?
A: LED compatibility depends on the specific fixture and driver. The DIN-1DIMU4 supports dimmable LED loads in mode-dependent configurations with minimum loads of 15-50W per channel. Compatibility testing with specific LED products is recommended before full deployment.

Q: Can the DIN-1DIMU4 be used without a Crestron processor?
A: No. The DIN-1DIMU4 operates in Cresnet secondary mode and requires a Crestron processor (such as the DIN-AP4-R or MC4-R) to send control commands. It cannot operate as a standalone dimmer.

Q: What is the maximum load per channel on 240 VAC?
A: At 240VAC, each channel of the DIN-1DIMU4 is rated at up to 1150W (5A). The total module load is limited to 2300W (10A) across all 4 channels combined.
