PD480 Low-Cost Loop-Powered Digital Panel Meter
Low-cost loop-powered digital panel meter
The PD480 is an affordable, loop-powered digital panel meter with a large display and compact design. It accepts a 4-20 mA input that can easily be scaled to engineering units in the field using the zero and span potentiometers. The meter comes equipped with a 3½ digit LCD and a loop-powered backlight.
Being loop-powered eliminates the need for additional power lines, reducing costs. The meter draws all the required power from the 4-20 mA loop, with a minimal 1.5 V voltage drop, ensuring a low impact on the loop.
This meter operates in a broad temperature range from 0 to 50°C (32 to 122°F). Calibration is simple and quick, involving just a two-step process with the adjustment of high and low non-interacting potentiometers.
