The LP400 Loop Powered Display provides digital  indication of a 4/20 mA or 10/50 mA process loop signal. The display takes its  operating power from the loop current and requires no other source of power.
                  Wide-ranging zero and span adjustments plus switch  selectable decimal point location and trailing zero allow the display to be  calibrated in engineering units. A front panel Engineering Units/Loop Current switch  permits a quick check of the process signal without recalibration.
                  Designed for field mounting, the LP400 is splashproof and  corrosion resistant and operates from -40 to 185°F (-40 to 85°C). The circuit  board is conformal coated for protection from humidity and contamination. Optional  accessories include a pipe mounting kit.
                  TYPICAL APPLICATIONS
                    Displaying process variables where line power is NOT  available.
