Loop-powered Panel Meters & Isolator/Alarms with Display
Acromag Vertu® Series VPM2000 loop-powered isolators/alarms with display are 1/8 DIN digital panel meters designed for the purpose of convenient and informative displays of any 4-20mA signal. The dual line display shows the process value on the top line and the units or a tag on the bottom line. You can also display the input in one scale on the top line (e.g. height) and another scale on the bottom (e.g. 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 4-20mA analog output. Furthermore, 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 greatly simplified as the meters acquire power from the 4-20mA 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. Additionally, intrinsically safe and non-incendive versions allow installation in hazardous areas.
Setup is fast and easy due to the front panel buttons and the free configuration software. A micro USB cable connects the meter to the PC and provides power for software-based programming and saving the file. The push buttons also serve as programmable function keys to change displays, reset min/max readings, acknowledge alarms, and other uses.
