Housed in a wall-mount, watertight
plastic enclosure, the DPS3301 is a
powerful temperature monitor/indicator
that accepts a single thermocouple,
RTD, or 400 Series thermistor
sensor input and then displays the
temperature in either °C or °F. In
addition, it monitors a number of
important functions, such as high
and low process readings,
process run time, and rate of
process change.
Four (optional) process alarms are
available that are programmable
over the entire range of selected
input type. They can be configured
as latching or non-latching, normally
open, or normally closed. Also
available are 2 optional timers that
work independently or in
conjunction with process limits (e.g.,
turning on a fan 10 minutes after
limit 1 temperature is reached). The
time function keeps track of process
run time.
The DPS3301 can function as a rate
monitor, indicating instantaneous as
well as average rate of temperature
change. Programmable time base
allows the rate to be displayed in
per second, minute, hour, or any
other interval. The DPS3301 can
also be programmed for a rate
alarm, which can indicate whether a
predetermined rate is exceeded or
not achieved.
The DPS3301 can be programmed
to indicate in 1 of 7 display modes:
- Display Process
- Display Rate of Change
- Display Deviation
- Display Max Reading
- Scan All Parameters
- Display Min Reading
- Display Elapsed Time
If scan mode is selected, all the
above parameters are briefly
displayed in sequence. Dwell time
for each mode is programmable.
Additional features include a built-in
buzzer that sounds whenever a limit
is reached (available with the relay
option). Visual indication of relay
output status is given by LEDs on
the front panel. A watchdog timer
keeps track of any runaway programs
caused by excessive noise or other
malfunctions. The DPS3301 also has
a power line filter designed to provide
trouble-free operation in harsh
industrial environments.
