Digital timers are manufactured by prestige electronics. These digital timers are used to cover ranges of 99, 999, 9999 milliseconds, seconds and minutes, suitable for applications such as on delay, off delay, unequal cyclic, and equal cyclic. Following are some of the technical features of these digital timers which include: time setting is provided with the help of 2, 3 or 4-digit thumbwheel switches. In case of cyclic timers 2+2 or 3+3 thumbwheel switches are provided. These timers are available in panel mounting size of 96 x 96 x 150 mm with or without digital display. Accuracy is better than 0.05% with crystal controlled time base. Output available is two changeover relay contacts rated for 6 a resistive load. Supply voltage range is 180 to 275 v ac.
