ET90000 Series 365-Day Astronomic Electronic Control, 4x SPDT

Product Description
The ET90000 Series 365-Day Astronomic Time Switches feature independent, 365-day programming that meet the demanding needs of any facility schedule. These state-of-the-art time switches provide reliable performance with to-the-minute accuracy that reduces energy costs. Superior memory accommodates up to 4,000 set points or events, plus holiday and exception programming. Easy-to-use control buttons permit independent manual control of each circuit regardless of the operating mode.

The intuitive time switches automatically detect and adjust voltage between 120 and 277 VAC, and operate at 50 or 60 Hz, which eliminates the need for manual voltage adjustments during installation. Exceptional versatility enables circuits to be added after installation. Automatic Daylight Saving Time feature can adjust the clock and the programmed schedule throughout the year. All models are equipped with a powerful 100-hour supercapacitor that maintains dates and times during a power outage and then automatically recharges in less than 30 minutes after power is restored. Software updating is made easy with the USB connection and Ethernet capabilities that enable in-field firmware upgrades to be installed remotely from one central location. These powerful time switches can be used with external devices such as wall switches and occupancy/vacancy sensors to manually turn ON and time OFF.

All models are securely housed in a lockable enclosure to protect against unauthorized entry, thus keeping the invaluable time switches under your control.
