Display, DC Voltage Monitors

MPM_DMS_20PC_0_DCM.E03 Page 1 of 2

FEATURES

Self-powered, only two connections required

+4.50-19.99Vdc, +8.0-50.0Vdc, +30.0-199.9Vdc

and +30-264Vdc models

Ideal replacements for analog panel meters

Ultra-low power consumption (8mA typ.)

0.37"/9.4mm high, red or blue, LED displays

Subminiature 1.38" x 0.88" x 1.0" packages

Super reliable, epoxy-encapsulated, construction

　

Brass screws (6-32 thread) and a panel-mount retaining clip are supplied with each mete

r

Operation and accuracy at inputs above or below these ranges

are not specified.

DATEL's DMS-20PC-DCM Series of self-powered, positive-reading, dc voltage monitors

are great replacements for older, hard-to-read, analog panel meters. Simply connect

a positive dc voltage across the rear terminals and the

meters are fully operational — no additional components

or power supplies are required! The large, 0.37"/9.4mm,

LED displays can be easily read from 15 feet away. Four

versions are available: +4.50-19.99Vdc (0.01V resolu-

tion), +8.0-50.0Vdc (0.1V resolution), +30.0-199.9Vdc

(0.1V resolution) and +30-264Vdc (1V resolution).

Built-in reverse polarity protection assures simple,

trouble-free installation.

All DMS-20PC-DCM's employ a high-resolution, 3½

digit A/D converter and precision metal-film resistors

to achieve outstanding performance over an operating

temperature range of –25 to +60°C. A rugged, epoxy-

encapsulated, polycarbonate case provides excellent

protection against moisture, shock and vibration. The

DMS-20PC-DCM's are designed to fit the same panel

cutout as DATEL's popular DMS-20PC-X-LM ac-line

voltage monitors
