Digital timers simplify your life by automating repeating parts of your schedule, saving the user time, energy and money. The EWZ120 is a 7-day astronomic lighting control timer, ideal for applications in the home, office, factory, church or school. Use a photocell sensor to detect when the ambient light level drops below a programmable threshold, then turn on everything from signage to meeting room lights. Program in up to 20 different on/off settings with unique schedules for each day of the week using the simple interface in order to control equipment exactly as needed. In addition to the astronomic sunset/sunrise programming and the customizable schedule, the EWZ120 also features automatic daylight savings and leap year adjustment and a manual override. This timer features 1 output channel and contains a supercapacitor that provides 4 days of backup power in the event of a power outage. Additionally, the inrush current limiting technology protects the relay contacts in the event of a surge. Choose a digital timer from TORK, a pioneer in the time switch industry since 1922.
