QUARTZ
CRYSTAL ACCURACY
This instrument
is accurate to within one second a day
Independent
Control of Open & Closed Time
The Model 825
features independent control of both open and closed time in one
second increments from 1 to 999 seconds. The Model 825 provides
almost infinite variation of time cycles and will accommodate
virtually every interrupter application.
Simple
Programming of Timing Cycles
The timing
cycles are programmed with digital thumb wheel switches. This
instrument can be synchronized with the second hand of a watch.
Two or more Model 825's can be sequenced and the timing of each
can be accurately predicted.
Electronic
Synchronization
Any number
of 825's can be electronically synchronized with each other and
resynchronized in the field.
No
Contacts to Wear or Burn
Current interruption
is accomplished by a mercury displacement 75 ampere relay. It
has no contacts to wear or burn. Indicator lamps show when the
relay is open or closed.
Powered
by 12 Volt Source
The Model 825
is powered by a 12 volt lantern battery through a panel plug.
An external 12 volt source can also be used. A battery warning
light is provided. When the indicator lights the battery should
be replaced. Model 110 is recommended.
