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
