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.
