- Automatic on/off control for operation at same time each day
- Digital 24-hour display with up to 20 on/off cycles each day, one-minute minimum cycle, manual override switch
- Automatic compensation for daylight saving time and leap year
- 120-277 VAC input voltage for multiple uses
- Noryl plastic alloy indoor/outdoor enclosure with locking hasp
This NSi Industries E103B digital time switch accepts 120-277 VAC input and its DPST output contacts can activate a 40 amp load or 2 hp motor. The switch automatically detects the input voltage and does not require manual voltage setting. This multipurpose timer includes 20 pairs of on/off set points, has a minimum cycle time of one minute, and is suitable for use where on/off operation is required at the same time each day. This timer can adjust for daylight saving time and leap year. A rechargeable super capacitor provides four days of backup power to maintain time and schedule settings. The double-pole single-throw (DPST) contacts are housed within a Noryl plastic alloy enclosure that meets NEMA-3R standards for water resistance and has a lockable hasp. The enclosure is suitable for indoor and outdoor 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.
