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:

  1. Display Process
  2. Display Rate of Change
  3. Display Deviation
  4. Display Max Reading
  5. Scan All Parameters
  6. Display Min Reading
  7. 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.
