The DMS-30PC Series is a broad line of self-contained, fully operational, 3�½ digit volt-
meters with large, easy-to-read LED displays. The 0.56"(14.2mm) high LED's are available
in a wide variety of colors including red, orange, amber, yellow, green, aqua, blue-green, and
super-blue. A high-intensity version of the red display is optional, as are low-power versions
of the red, orange, and green displays.
The small size (2.17" x 0.92" x 0.56") of DMS-30PC meters is achieved by integrating
their display, display drivers, reference circuit, and A/D converter into in a single, epoxy-
encapsulated assembly. The device's 12-pin, component-like, DIP package is both vibration
and moisture proof. Each package incorporates a built-in color filter and bezel and is easily
mounted in either panels or pc cards.
These meters are available in four differential input voltage ranges (±200mV, ±2V, ±20V
and ±200V). Input impedance is 1,000 megohms for the ±200mV and ±2V inputs and 1
megohm for the ±20V and ±200V inputs. CMRR for all devices is 86dB, and inputs are
overvoltage protected to ±250V.
Each meter incorporates an extremely stable, double-regulated reference and is fully
calibrated prior to potting. We guarantee outstanding initial accuracy (±1 count) and
excellent stability (±0.15 counts/°C). All models operate from a single +5V supply, and the
low-power models draw as little as 10mA (50mW total power). A DISPLAY TEST function is
standard on each device.
For popular applications (4-to-20mA, rms-to-dc conversion, ac line power, J and K ther-
mocouples, etc.), the DMS-30PC Series includes a complete line of optional "plug-on" appli-
cation boards that conveniently convert your meter into an application-specific instrument.
