The Vantageview PD6770 is a rugged, loop-powered meter with 1" display digits. The plastic NEMA 4X and IP66 field mountable enclosure is designed for demanding applications in the harshest environmental conditions. The meter derives all of its power from the 4-20 mA loop with a small 1 volt drop for easy installation in almost any system. The meter is programmed using four easy to access front-mounted potentiometers with no complex or difficult to read programming menus necessary for setup. The numeric display will read from -1000 to 1999 over a 2000 count user adjustable scaling span. The backlight option lets you see the display under any lighting condition and is powered from the 4-20 mA loop with no additional power supply required. The enclosure is provided with three threaded conduit holes and integrated pipe or wall mounting slotted flanges.

Why Use Loop-Powered Meters?

The most basic decision a user wishing to display a 4-20 mA signal on a digital display has to make is: should the meter be powered by line voltage or should it be powered by the 4-20 mA loop?

There are three main benefits of using loop-powered devices:

  • No additional power required
  • Easy wiring
  • Additional digital displays can easily be added in the same loop

The following diagram illustrates how a loop-powered meter is wired. Notice there are only two connections made to the meter.
