Acromag Vertu VPM2000 digital panel meters

Acromag Vertu VPM2000 loop-powered 1/8 DIN digital panel meters are designed to provide a convenient and informative display of any 4–20 mA signal. A dual line display shows the process value on the top line and the units or a tag on the bottom line. Alternatively, users can display the input in one scale on the top line (eg, height) and another scale on the bottom (eg, volume). A bar graph option indicates the percentage the value represents.

All models include a digital input and two open collector outputs. For signal isolator and alarm trip applications, model options add two solid state relays or 4–20 mA analog output. The digital input enables remote reset or triggering of alarms. Open collector outputs are useful for alarm indication or pulse output. Relays support alarm activation, on/off control and pump alternation functions.

Installation is simplified as the meters acquire power from the 4–20 mA loop and therefore require no separate power source. A low voltage drop adds very little burden to the loop. The NEMA 4X IP65 panel, conformal-coated PCBs, wide temperature operation and a backlit LCD enable use in most environments. Intrinsically safe and non-incendive versions allow installation in hazardous areas.

Set-up is fast and easy using the front panel buttons or the free configuration software. A microUSB cable connects the meter to the PC and provides power for software-based programming and saving the file. The pushbuttons also serve as programmable function keys.
