  Over Voltage Protected: ± 30 VDC

OPTO-ISOLATED DC PULSE INPUT

  High (logic 1): 4-30 VDC

  Low (logic 0): Less Than 1 VDC

  Minimum Current: .5 mA

  Hysteresis: 0.4 VDC

  Frequency Range: 0 to 5 kHz  

  Min. Pulse Width: 0.1 msec

CONTACT CLOSURE INPUT (contact closure to common)

  Internal Pullup Resistor: 100 KΩ to +3.6 VDC

  High (logic 1): Open or 4-30 VDC

  Low (logic 0): Less Than .5 VDC

  Internal Switch Debounce Filter: 0 to 40 Hz

NOTE:   Sustained contact closure will shorten 

   

battery life.

RESET INPUT (contact closure to common)

  Internal Pullup Resistor: 100 KΩ to +3.6 VDC

  High (logic 1): Open or 4-30 VDC

  Low (logic 0): Less Than .5 VDC

  Minimum On : 25 msec

battery life.

  Range: 0.001 to 99999999

  Decimal Point Locations: XXXX.XXXX to XXXXXXXX

  This  feature  allows  the  user  to  enter  20  different  frequencies 

with 20 different corresponding K-Factors to linearize non linear 

signals.

  Type: 4-20 mA follows rate display, Two wire hookup

  Accuracy: 0.025% Full Scale at 20° C

  Temperature Drift:  50 ppm/°C Typical

  Reverse Polarity Protected

  Update Rate: 8 times/second

NOTE: The DPF500 uses the 4-20 mA loop power as its primary 

power source when this option is used.  The battery is still 

required for standby battery operation.

  Setup Information: Stored in fl ash memory

  Totalizer:  Stored  in  battery  backed  RAM  but  can  be  saved  to 

fl ash memory by operator for recall after battery change out.

Life expectancy based on rated battery capacity at 20°C

 

The above table is shown with pulse output inactive. Use 

of pulse output shortens battery life.

 

Example: A pulse output of 0.06 sec. duration, once per 

second, would derate the battery life by 20%.
