Murata Power Solutions’ new DMR20-0/5 Series are the world's first 0-5V input
process monitors designed to fit industry standard, 1.21 inch [30.7 mm] round panel
cutouts. Their large, easy-to-read, 0.30 inch [7.6 mm] digits are available in a choice of
red or green LED displays. For the ultimate versatility in industrial applications, these
new process monitors can be operated from any regulated source of 5V, 12V, 24V, or
36V dc power.
Gain (span) and offset (zero) adjustments are performed with on-board, precision,
20-turn potentiometers. All decimal-point and range-change selections are made on a
6-position, vibration-resistant, gold-plated DIP switch. Unlike competitive meters, there
are no jumpers or solder gaps to open or close. To further enhance reliability, the
entire assembly utilizes 100% soldered connections. Both power-supply and input-
signal connections are made via a reliable, 3-position, screw-type terminal block.
The DMR20-0/5's DIP switch and potentiometers accommodate hundreds of input-
voltage / output-reading combinations. This practically eliminates the need for more costly,
long-lead-time, factory "customs" in applications which use several different-range meters.
An EPDM rubber gasket and hex nut simplify installation and provide IP67 / NEMA 6
protection to environmental dirt and moisture, including water submersion to 3 feet (1
meter).
