Campuses, municipal sites and large retail properties can run a dozen or more lighting and equipment zones off separate clocks, each drifting on its own. The Intermatic ET91615CR is a 16-circuit, 365-day astronomic time switch from the ET90000 series that puts all of them on one controller with sunrise and sunset tracking, holiday schedules and Ethernet included. It runs on 120-277 VAC and comes in an outdoor Type 3R steel enclosure.
Why controls contractors pick it
- 16 relay circuits, set up as 16 SPDT or 8 DPDT, in one enclosure.
- Astronomic 365-day scheduling with holidays and relative dates, for 2,000+ events.
- Ethernet included for remote schedule changes and overrides; USB for copying programs.
- Automatic input voltage detection from 120 to 277 VAC, 50/60 Hz.
- 100-hour supercapacitor carryover with non-volatile program memory, so no battery.
- Firmware upgradeable in the field via USB or Ethernet.

Pro tip from the counter
The normally closed side of each relay is rated far lower than the normally open side (3 A ballast, 10 A resistive). If you plan to wire any lighting fail-on through the NC contacts, size those circuits to the NC ratings or drive a contactor instead of the load directly.
Best for: school boards and campuses, municipal buildings and parks, large retail and parking sites, multi-zone site, sign and HVAC scheduling
