Timer REV-303 is a microprocessor-based programmable device designed to control the loads in real time without permanent maintenance with minimum expenses and maximum electricity saving. Timer REV-303 can be used to switch on the heating system, pumps, fans, school signals, street illumination, highlighting of buildings fronts (around territories, car parking and other objects). Timer REV-303 can automatically define the time of sun rise and sun set on the basis of entered coordinates and current time which enables to control the illumination (street light) without using the external sensors.
Timer REV-303 features:
Every day the timer calculates the real time of sunrise and sunset, sums this time with the time of event, and then the resulted time is referenced with the clock of real time and if the resulted time is more or equal to real time – the time will switch the load relay in state which is assigned by the event.
The above described algorithm is performed for each event planned by the user. In case when there are more than 1 event planned, only the event which corresponds to the real time clock will be activated, other events will not be performed. At the latitudes where there is a polar day, the events concerning the sunset will not be performed and the time of the sunrise is taken as equal to 00:00. At the latitudes where there is a polar night the events concerning the sunrise will not be performed, and the time of the sunset is taken as equal to 00:00.

RN-16TM Daily-Weekly Timer combines the following functions:
And is designed for:
The relay provides for the following modes of operation:
The LEDs on the relay front panel indicate:
The four-digit, seven-segment display depending on the operation mode displays:
The photosensitive diode which monitors the illumination intensity is installed on the device front panel. An external photosensitive diode connection is also possible.
The RN-16TM relay output terminals can immediately switch wattage load of up to 3.5 kW (16A). When it is necessary to switch greater wattage, a magnetic starter should be utilized.
The device menu allows:
In case of mains voltage loss, the built-in battery allows storing the set parameters within one month period.
