Outdoor Set-to-the-Minute High-Current Time and Day Activated Switches

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing. More precise than other time and day switches, they program on/off times for equipment down to the exact minute. They control equipment with high currents, such as landscape lighting, pumps, and heaters. A backup battery maintains the program during a power outage.

7-Day Timing Cycle—Seven-day switches can perform a different program each day of the week.

365-Day Timing Cycle—Seven-day/365-day switches can perform a different program each day of the week or year, and compensate for leap year and daylight savings time. Override regular programming for up to 99 holidays for any length of time. They can also be used to activate equipment such as bells and signals for just a few seconds.

Astronomical Timing—Switches with astronomical timing can be set to turn lights on and off based on sunrise and sunset.

Preventative Maintenance and Inspection Indicators

Mount these indicators to your equipment, and their bright LED will catch your attention when it’s time for maintenance or inspection. They’re commonly used to keep track of maintenance on production lines and HVAC systems, or paired with inspection tags on fire extinguishers and eye wash stations.

When first set, these indicators flash a dark green and then a light green color every two minutes. As a scheduled inspection approaches, they flash a yellow light every 10 seconds. And when an inspection is past due, they blink red every two seconds. Reset indicators to start the countdown again. They meet IP65, so they seal out dust and low-pressure washdowns.
