New Loop-Powered Isolator/Alarm with Large LCD Display Streamlines Installation and is Certified Non-Incendive Intrinsically Safe

Acromag’s newest digital panel meters are powered by the 4-20mA loop with options for isolated analog output and/or solid-state relays.

The newest addition to Acromag’s Vertu™ brand of innovative instrumentation is the VPM2000 Series of loop-powered display meters with process current output and alarm capabilities. These instruments supplement the digital indicator functions of a panel meter with optional 4-20mA isolator output and/or alarm trip solid-state relays. A dual-line LCD display has large 0.7 inch digits, an optional bargraph, and a backlight for clear visibility in bright sunlight or dim lighting. The backlight glows red and flashes under alarm conditions. No separate power supply is required for easy installation almost anywhere. They are even UL/cUL approved for use in hazardous locations requiring intrinsically safe, non-incendive devices.

The VPM2000 displays are simple to set up and install. USB connection to a PC makes setup fast and easy with the free configuration software which can save the file for copying to other units. Front-panel pushbuttons can also set operating parameters and serve as function keys to change the display or acknowledge alarms. A shallow-depth 1/8 DIN enclosure with a NEMA 4X IP65 front panel facilitates mounting. Internal PCBs are conformal coated for protection from the elements while a -40 to 75°C operating range enables use in extreme environments.

“These versatile instruments combine the functionality of a 4-20mA signal isolator, a dual-relay limit alarm, and a digital display in a single unit that is powered off a process current loop” explains Robert Greenfield, Acromag’s Business Development Manager.
