Brass screws (6-32 thread) and a panel-mount retaining clip are supplied with each meter
➀ Operation and accuracy at inputs above or below these ranges
are not specifi ed.
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 posi-
tive 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 ver-
sions are available: +4.50-19.99Vdc (0.01V resolution),
+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-fi lm 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 fi t the same panel
cutout as DATEL's popular DMS-20PC-X-LM ac-line
