Housed in a wall-mount, watertight
plastic enclosure, the DPS3311
accepts a linear voltage, current, or
millivolt signal at its input; converts
this into desired engineering units;
and then displays the result. In
addition, the DPS3311 monitors a
number of functions, such as high
and low process readings, change
in process value from any given
point, process run time, and rate of
process change. Input signals are displayed in
engineering units that correspond to
the process being monitored. For
example, if measuring pressure, the
input signal can be scaled to give
the reading directly in psi. Scaling is
done using the front keys and does
not require tedious formulas. A tare
function is included for weighing and
similar applications.
For control and alarm functions, the
monitor has 4 programmable limits.
A built-in buzzer sounds an alarm
whenever a limit is reached and any
relay is activated (available with output
option). Other features are process
run-time indication and 2 (optional)
timers with outputs. One of the
process outputs can be configured
as a process change alarm, another
as a process rate alarm. The
process change alarm activates
when a process deviates by a
programmed amount from a reference point. The rate alarm
activates when a preset rate is
exceeded or not achieved.
The DPS3311 Series monitors can
be programmed to indicate in 1 of 8
display modes:
If scan mode is selected, all the
above parameters are briefly
displayed in a sequence.
Input, power, and output connections
are conveniently located in a
separate terminal compartment and
are made through pluggable
Euro-style screw terminals.
