Programmable Astro Timers

The Programmable Timers with Photo Relay and Voltage Monitor are designed to energize/de-energize one or two loads within user set time intervals based on the circuit voltage and the external photo sensor illuminance. The devices’ output terminals can immediately switch wattage load of up to 3,5 kW (16A). Power supply: 230V/50Hz AC or 24V DC (for REV-302.01 relay).

Programmable Astronomical Timer With Photo Sensor and Voltage Protection.

 

REV-302 multifunctional relay is a microprocessor based programmable device designed to energize/de-energize one or two loads within user set time intervals based on astronomical logic, yearly timer, weekly timer, daily timer, simple timer logics, circuit voltage (over & under voltage) and external photo sensor (illumination intensity) basis.

 

Specific features of REV-302:

 

  • Two potential free switching contact groups (two channels) of 16A @ 250V AC rated current
  • Power supply: 90 - 420V 50/60Hz AC, 100 - 300V DC or 8 - 30V DC battery
  • Time relay, voltage relay and photo relay combined or independent operation
  • Flexible contact switching control transfer between the voltage relay, the photo relay and time relay
  • 8 independent control programs and capability of swift transfer between them for each contact group
  • Common internal memory for 5000 independent events distributed between all programs for day/week/month/year mode depending on the mode selected
  • Option of controlling both terminal groups with a single program or independently with two seperate programs
  • 10 year calendar (RTC) standalone power supply
  • Astronomical, Daily, weekly, monthly, and yearly time relay program
  • Independent timers settings lists for each program
  • Planned event clock accuracy of up to 1 second
  • Option for programmable holiday and day off list
  • Specific timer list execution for days off and holidays
  • Common built-in memory for 5000 independent timers distributed between all programs for day/week/month/year mode depending on the mode selected
  • Option of program cyclic repeat within a specified time interval
  • Automatic summer/winter time conversion
  • Pulse time relay function (periodic, calendar independent contacts close/open)
  • Function of plain contacts closure within a specified delay after energization
  • Contacts close/open based on minimum and maximum circuit voltage
  • Temporary delay for the after-energization relay start
  • Separate time delays for the voltage relay and the photo relay actions (for setting the reclosing time, etc.)
  • External photo sensor
  • LCD graphical display
  • Each channel status indication
  • PC connection USB interface
  • PC software with convenient graphical interface allowing to edit all relay settings and to create event arrays, or sunrise and sunset activated events
  • Multiple language interface
  • Menu control via 5 keys on the front panel
  • Loading preset control programs via USB with use of supplemental software
  • Password protection option for the settings menu
  • Common reset key on the front panel

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:

  • Two programs of control with quick switching over between them;
  • Four operational modes of timer (astronomic, weekly, daily and simple modes);
  • Calendar with operational life for 6 years period without external power supply;
  • Accuracy of planned events 1 second and 0.1 second in simple mode of timer;
  • Total internal memory for 500 independent events, divided between the programs;
  • Automatic shift for summer time and winter time;
  • Light-emitting graphic display (OLED);
  • Indication of current state of relays contacts;
  • Control of timer with 4 buttons, located on the front panel;
  • Possibility to set an access password for setup menu;
  • Power supply from the electric line 24 - 265 V 50/60 Hz or from DC source of 8-24 V battery;
  • 16A relay output 250V AC


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.
