产品描述
The DPS3311 series has been discontinued. Please see the CNi8C-EN series as a possible alternative. Some stock may still be available as shown in the "To Order" section.| 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:
Input, power, and output connections are conveniently located in a separate terminal compartment and are made through pluggable Euro-style screw terminals. |
