PROGRAMMABLE LIGHT-ACTIVATED TIMER

DESCRIPTION The LS7217 is a Programmable Timer IC designed to turn on a relay at night and turn off the relay at dawn or after a select able number of hours. Figure 2 shows a typical application schematic. The circuit is powered from a step-down transformer and the output drives low-voltage A
