DPM-400 | Digital Panel Meter

The DPM-400 loop-powered digital panel meter allows you to install a local display right where you need it. No power, no problem. This digital panel meter is powered by an existing 4-20 mA loop, making it an ideal display solution for any of your 4-20 mA sensors. It features a dual-line display with a 5-digit alphanumeric top line and an 8-digit alphanumeric bottom line. A common level sensor setup shows input by scale on the top line (such as feet and inches) and a description on the bottom line (such as silo number). Both lines use 14-segment, alphanumeric characters for clear indication of tags, units, or alarm messages. Choose from a general purpose decimal-display, a decimal display with a bar graph, or a feet and inches with a bar graph display. Digital Panel Meter Product Listing

• Input: 4-20 mA
• Power: 4-20 mA loop
• Display: Dual-line LCD with backlight. Both lines 14-segment alphanumeric. Top: 0.7″ (17.8 mm), Bottom: 0.4″ (10.2 mm). Display may be programmed to turn red and flash a user-defined message on alarm condition.
• Backlight: Powered by 4-20 mA loop. Intensity varies with signal level
• Display Update Rate: Ambient > -10°C: 1 update/second; Ambient = -20 C: 1 update/2 seconds; From -20°C to -40°C the update rate slows down 1 second for every 2°C (e.g. at -24°C, 1 update/4 seconds).
