Description
The STW-5 and the STW-5R are up/down
timers that are functionally identical but are available in two case styles
depending on how and where the customer intends to use them: desk mount
or rack mount. The desk mount timer is housed in a rugged plastic case
with a sloping front and conveniently placed pushbuttons. It offers portability
so that the timer can be used anywhere in a facility. The
rack mount version is a stationary unit that offers the convenience of
being mounted into standard 19" rack frames. Both versions use 0.8" (20.3
mm), red LED displays with up/down LED indicators and are able to drive
at least 50 remote timer displays using a
simple 2-conductor shielded cable.
The STW-5R can be controlled remotely
(available upon request). All of the front panel control functions can be accessed
from the rear of the unit using a simple remote control or footswitch.
The functions of the timer are actuated by a contact to ground. Using a
remote control gives an operator the ability to control the timer from a
second location apart from where the main unit is located.
Both units use larger digits to display the hour, minutes
and seconds, and a smaller digit to display tenth of seconds. They operate
from the power line frequency 50 or 60 Hz, which gives an accuracy better than
0.1 seconds per hour. They can be loaded with any time including negative time
to the second, and count up or down from that time. They can also be preloaded
while they are running to cut down on loading times during production. They
can be set to continue counting past or stop at zero. Leading zero blanking
can also be set.
The local controls are as
follows:
|
