It is a digital time relay that includes a real-time clock, can calculate sunrise and sunset according to the geographic coordinates it receives from the selected city code or from manually set coordinate information, can be programmed manually between time zones with its flexible programming functions, and automatically controls its contacts in accordance with the programs stored in its memory.
Without the need for any sensors such as photocells, the device controls street, park, garden and summer lighting with high precision; it is also used for irrigation of parks, gardens and fields, and for lighting ATMs, shop windows, billboards and many similar applications.
The device has an opening that allows the battery to be replaced when it expires, and a super-capacitor as an additional backup, so that the stored programs and real-time information are protected from power failure. This backup ensures that the configured settings are preserved during a power failure and extends battery life, since no energy is drawn from the battery.
