Multifunctional programmable timer REV–303 NTRV30300

Multifunctional programmable clock – precise time control and automation

The REV-303 programmable clock is a versatile device that can be used in both home and industrial installations. It allows for automatic switching of electrical devices on and off, optimizing energy consumption and increasing user comfort. It is ideal for controlling heating, lighting (including outdoor), pumps, fans, and even school bells. Its capabilities also include advanced lighting scenarios, utilizing automatic calculation of sunrise and sunset times.

Flexibility and reliability in every operating mode

REV-303 offers four operating modes, tailored to different needs: astronomical (using sunrise and sunset data), weekly, daily, and simple (counting time from the moment power is supplied). The internal memory allows programming up to 500 independent events, divided between two control programs (P1 and P2), enabling quick switching between different schedules. Additionally, the clock has a function for automatic switching between daylight saving time/winter time, ensuring accurate time measurement throughout the year. Emergency time retention (up to 6 years at 25°C) guarantees that settings will be preserved even in the event of a power failure.

User comfort and safety

The REV-303 clock is equipped with a clear 128x64 pixel graphic display and intuitive control using four buttons. The ability to set an access code protects against unauthorized changes to settings. Mounting on a 35 mm DIN rail facilitates installation in electrical panels. The device operates in a wide temperature range (from -30°C to +55°C) and has a protection class of IP40, ensuring reliable operation even in harsh conditions. The power supply can come from both AC mains (24–265 V) and a DC voltage source (8–24 V), increasing installation flexibility. The relay with a load capacity of 16A/250V AC allows controlling most typical electrical loads.
