The EL71 and EL72 Series has It all. This two-relay
series has single-handedly replaced up to 5 controls and has every feature
an industrial, commercial or municipal application could possibly require.
The EL71 and EL72 can be used as 24-hour, 7-day, 365-day controls with
daylight savings time, leap year adjustment and selectable SunTracker™
controls. Y2K compatible, they are easy to program with each control
allowing up to 128 ON or OFF events, 34 holidays and 32 sensor
events.

FEATURES & BENEFITS
|
|
96-Hour Carryover, unique to Paragon, protects
scheduled events from power interruptions via a capacitor-more reliable
than batteries.
|
|
|
Resolution enhancements allow 4 user-defined duty
cycle patterns; 4 user-defined durations are available from I second to
23 hours, 59 minutes, 59 seconds.
|
|
|
ON/OFF events can be controlled by temperature,
light or other sensors.
|
|
|
Enabler switch allows an ON event to be selected
without pre-programming the event.
|
|
|
|
Pecosoft.EL software and CIMI Adaptor (each sold
separately) allow remote programmability.
|
|
|
User-friendly keypad and easy-to-read digital
time display take the frustration out of programming.
|
|
|
Remote override allows immediate reaction to
unexpected events without affecting pre-programming or visiting the clock
site.
|
|
|
UL and CSA listed means quality and durability
are built into every time control.
|
|
|
Title 24 certified.

HOW TO SPECIFY
How to Specify Installer shall furnish
and install Paragon EL71 single-channel (or EL72, two-channel) Electronic
Time Control. The control shall have 24-hour, 7-day, 365 day, or
SunTracker™ capability with 128 events available. It shall also have 4
user-definable durations and duty cycle lengths plus automatic daylight
savings time and leap year adjustments. Control shall have remote override
capabilities (timed, toggle or enable type.) Control shall have keyboard
override until overridden again or until next event is reached. It shall be

metal enclosure.
Frequency 50/60 Hz
Power Consumption 4 VA Max
Wiring Terminals Power input and relay contact terminals can
accommodate 10-16 AWG.
Sensor/override input terminals can accommodate 14-22 AWG UL Listed, CSA
Certified, and comply with FCC, part 15 rules.
Power Outage Carry-Over (No battery needed)
The program and time-of-day are maintained during a power outage for a
minimum of 7 days. A built-in, special capacitor eliminates the
inconvenience of battery replacement.
