Digital timers simplify your life by automating repeating parts of your schedule, saving the user time, energy and money. The DGUM100A is a 24 hour / 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 56 different on/off settings for each day of the week using the simple interface in order to control lights or appliances exactly as needed. This timer features 1 output channel, sized for #12 to #18 AWG wires and built with SPDT momentary output contact, with automatic detection between 120 and 277VAC, 50/60Hz. It is also rated for operating temperatures between -31Ëš and 131Ëš Fahrenheit, and for usage with 1-2HP motors. The supercapacitor provides 7 days of backup power in the event of a power outage, and 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.
