INTRODUCTION
The PD6870 is a rugged, loop-powered meter with 1" display digits in an explosion-proof enclosure for demanding applications in hazardous areas or 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 use in almost any current loop and application.
It is programmed using four easy to access front-mounted trim potentiometers. No complex or difficult to read programming menus are necessary for setup. The numeric display will read from -1999 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 has two threaded conduit holes, one pre-installed conduit plug, and integrated pipe or wall mounting slotted flanges.
