Data Sheet
DTR series astronomic time relays are smart time relays which are capable of automatically calculation of sunrise and sunset times
and have internal real time clocks.MCB-50/50t electronic time relays which have internal real time clocks are designed to control
devices according to the time periods programmed by the user.
They are used in lighting controls (streets, parks, gardens, and buildings), school bells, industrial heating/cooling systems and
agricultural irrigation.
