Acculex DP-670 Panel Meter

Acculex DP-670 Panel Meter is a compact, loop-powered 3-1/2-digit LCD meter designed to display 4–20 mA process signals in a panel-ready package. It features a 0.39-inch high-contrast LCD showing up to ±1999 counts, three selectable decimal points, and a snap-in bezel that fits a front-panel cutout of about 2.22 × 1.04 inches (roughly 2.3 × 1.1 inches of front-panel space). Optional SPAN (GAIN) and ZERO (OFFSET) adjustments are provided by the process-input board that mounts to the DP-670, with automatic polarity display and overload behavior that blanks the lower three digits for out-of-range signals. Electrical specs include loop-powered operation from a 4–20 mA current loop, a nominal loop burden of 300 Ω at 20 mA, 0–50°C operating range (−10 to 60°C storage), conversion rate of 3 readings per second, depth of 0.67 inches (17 mm) with process-board mounting adding about 0.6 inches to depth, and accuracy of ±0.1% + 1 count typical (±0.2% + 2 counts max).
