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
