        DIN-1DIMU4

        4 Channel Universal Dimmer, 1 Feed, DIN Rail Mount

        • 4 channels of forward or reverse phase dimming
        • Auto load detection
        • 120 to 240 Volt 50/60 Hz operation

        Visit the Crestron® Lighting Fixture Compatibility page to find out which Crestron lighting devices have been tested and are compatible with third party lighting fixtures.

         

        The Crestron® DIN-1DIMU4 is a 4-channel universal lighting control module designed to support dimming of both forward and reverse phase type loads. A single model supports both 120V and 220-240V electronic and magnetic low-voltage, incandescent, neon/cold cathode, 2-wire dimmable fluorescent, and non-dimmable lighting loads up to 5A per channel, 10A total.

        Auto Load Detection

        Each channel of the DIN-1DIMU4 is capable of auto-detecting the dimmable load type connected to it and selecting the appropriate operating mode to control that load. Reverse phase (trailing edge) mode supports incandescent and electronic low-voltage load types, while forward phase (leading edge) mode handles magnetic low-voltage, neon, and other inductive load types. A non-dim mode is also selectable for switching of non-dimmable lighting fixtures. Any channel may be set for any mode, allowing one dimmer module to handle any combination of lighting types on four separately controlled circuits.

        Phase-Synchronous Detection Circuitry

        Proprietary zero cross filter technology provides superior immunity to noise on the power line, reducing lamp flicker, and compensating for fluctuations in line voltage and frequency.

        Short Circuit Protection

        Built-in OCP (overcurrent protection) prevents failure of the DIN-1DIMU4 caused by excessive loading or improper wiring of the outputs.

        Primary Air-Gap Relay

        When all four channels are turned fully off, the internal master relay automatically opens providing air-gap isolation to allow safe servicing and changing of light bulbs on all four controlled circuits.

        Override Input

        An override input is provided to allow an external contact closure to momentarily override the control system program and set each channel output to its override preset level. Levels can be adjusted and saved locally from the front panel or remotely via software.

        DIN Rail Installation

        The DIN-1DIMU4 is designed to snap onto a standard DIN rail for installation in a wall mount enclosure. Wiring connections are made using screw terminals positioned along the bottom, clearly accessible from the front for easy installation and servicing. All setup controls and indicators are positioned on the center front panel. When installed in an enclosure utilizing 45 mm cutouts, the DIN-1DIMU4's front panel stays accessible while the connections are concealed.

        Cresnet® Wired Communication

        The DIN-1DIMU4 communicates with a Crestron® Control System using the Cresnet control network. A pair of Cresnet ports is provided on the DIN-1DIMU4 allowing for easy daisy-chaining of several DIN Rail Series automation control modules.
