Selco/ECC’s PET 1481 Programmable Electronic Timer has
been designed to provide exceptional control versatility
offering the user full programmability of both operating control
mode and time delay period.
before or after installation by setting switches on a
conveniently located 8 position, digital (DIP) switch and by
fine tuning with the external potentiometer knob.
Standardizing on this one versatile timer, the user can stock a
single part that can handle all time delay control functions.
Conversion from a Delay-On-Operate to Interval-On (or any of
the 5-modes of operation shown) can be accomplished in a
few seconds, without unplugging the unit and with no special
tools.
By programming the 8-position DIP switch there are 62
possible combinations of the timing range.
switch position #8 only, for example, the timing range would
be set at .3 to 2.75 seconds. With all switch positions ON, the
range is 1457 seconds to 8060 seconds. An instruction sheet,
packaged with each unit, shows typical ranges and how to set
additional ranges to maximize your actual application.
The PET 1481 uses a special P-MOS digital timing IC
combined with other advanced circuitry to provide exceptional
accuracy and long life. The output device is a standard hi-rel,
DPDT enclosed relay with proven mechanical life in excess of
10 million cycles.
