Location:
ET8415CR
Product Type:
7-Day Electronic Astronomic Time Switch
Contact/Phone:
The ET8415CR 7-Day Astronomic Time Switch features independent
7-Day programming to provide flexibility for applications where load
Model #:
switching differs each day of the week. This time switch provides
dependable and uncomplicated performance, plus to-the-minute
programming for accurate load control and reduced energy costs. Up to
28 ON/28 OFF (56 events) can be preset to automatically repeat. Each
event can be applied to any combination of circuits and days. Each
circuit is provided with an independently scheduled Astronomic ON
event and Astronomic OFF event. The program can be disabled at any
time by placing the time switch in the Manual operating mode. Control
buttons provide manual control of each circuit independently regardless
of the operating mode. The ET8415CR comes with a 100 hour
supercapacitor to provide time keeping and automatic carryover with
no maintenance. The time switch is housed in a lockable enclosure to
protect from vandalism and unauthorized tampering.
Features
• Program can be repeated on a weekly basis
• Auto-voltage operation from 120-277 VAC, 50/60 Hz
• To-the-minute programming for accurate load control and reduced
energy costs
• Astronomic feature provides sunset ON and sunrise OFF settings to
eliminate the need for separate photo control devices
• Astronomic programming can be combined with independent
programs to provide a sunset ON and timed OFF program
• Each pair of relays is independently software configurable for:
2 independent outputs, DPST output, or 1 channel ON pulse OFF
pulse output
• Up to 28 ON/28 OFF setpoints or events and 8 Astronomic events
• Sunrise/Sunset Astronomic events can be distributed throughout the
days of the week
• Automatic Daylight Saving Time (DST) ON/OFF adjustment
(factory enabled)
• Non-volatile EEPROM memory protects programming indefinitely
• Temporary override or permanent manual override available via control
buttons

Specification
The 7-Day Astronomic electronic-type time switch shall be capable of permitting up to 28 ON/28 OFF events. In
addition, the time switch shall include selectable Astronomic (sunrise/sunset) settings for each day and circuit to allow
load switching at sunset and/or sunrise without a photo control device. The time switch shall provide a minimum ON or
OFF time of 1 minute. The time switch to be powered by ___ (120)(208)(240)(277) VAC, ___ (50)(60) Hz power supply. The
time switch mechanism features a snap-in design to provide easy mechanism removal for mounting the enclosure. The
time switch enclosure shall be a Type 3R Steel lockable enclosure that shall be painted with an electrostatic process to
eliminate the potential for corrosion. The time switch shall provide clear terminal identification on a see-through
non-curling terminal insulator. Terminal connections shall provide secure connections for wire sizes up to #10 AWG.
Switch configuration shall be _____ (SPST)(DPST) with a UL or CSA listed switch rating of:

There are many different ways to set the relays on the
ET8415CR Time Switch. The four relays can be used
individually or in pairs of two. Refer to the table below for a
complete list of ways to set the relays and the illustrations
