PD684 Loop Leader Loop-Powered Flow Rate/Totalizer Digital Panel Meter

Brand: Precision Digital Corporation
The Loop Leader PD684 is a loop-powered, 1/8 DIN flow rate/totalizer designed for demanding process control applications. 

The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The PD684 loop-powered rate/totalizer is built in a shallow-depth case with an FM Type 4X front and features loop-powered backlighting and a wide -30° to 65° C operating temperature range.

It doesn't matter if it's indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.
Features
  • 4-20 mA Input
  • 5-Digit LCD, 0.6" (15.2 mm) High
  • Overflow Displays Total up to 8 Digits
  • Programmable Alternating Rate/Total Display
  • FM Type 4X, IP65 Front
  • Shallow Depth Case 3.2" Behind Panel
  • 2 V Drop (5.7 V with Backlight)
  • Loop-Powered Backlight Standard
  • Custom Engineering Units & Bargraph
  • Square Root or Programmable Exponent
  • Non-Volatile Memory - No Battery Needed
  • Maximum & Minimum Display
  • Operating Temperature Range: -20° to 65°C
  • Open Collector Alarm or Pulse Output
  • HART Protocol Transparent
