About DGU Series Lighting Control With Photo/Override
This NSi Industries DGU100A-Y digital time switch accepts 120-277 VAC input and its DPDT output contacts can activate a 20 amp load or 2 hp motor. This timer includes 56 pairs of on/off set points, has a minimum cycle time of one minute, and is suitable for individualized daily operation. A rechargeable super capacitor provides seven days of backup power to maintain time and schedule settings. This timer can adjust for daylight saving time and leap year and can track nine holidays. The double-pole double-throw (DPDT) contacts are housed within a metal enclosure that meets NEMA-1 standards for dust resistance and has a lockable hasp. The enclosure is suitable for indoor use and mounts to an external surface. This digital timer is Underwriter Laboratories (UL) Listed and Canadian Standards Association (CSA) certified for quality assurance and is suitable for controlling lighting, heaters, and equipment motors.

Time activated switches (also known as timers) operate at preset time intervals during a daily or weekly period and can be either mechanical or electronic. Mechanical timers feature a dial with multiple pins to set the on/off time intervals. Electronic timers feature an LCD display and pushbuttons to set the time intervals. Light activated switches (also known as optical or photo) operate when ambient light levels reach preset values, generally measured in foot candles. Motion-activated switches (also known as motion sensors) operate when an electronic field of a preset range is interrupted. These switches can include energy saving logic that uses combinations of time, light, and motion to operate and can include one or more device outlets or circuit contacts. Automatic switches are used to control indoor lights, outdoor lights, appliances, and small equipment motors. NSi Industries manufactures electrical components and sensors, lighting products, and energy management products. The company, founded in 1975, is headquartered in Huntersville, NC.
