The DMS-30PC Series is a broad line of self-contained, fully operational, 3? digit volt meters with large, easy-to-read LED displays. The 0.56(14.2mm) high LEDs 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 devices 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 (¡À200mV, ¡À2V, ¡À20V and ¡À200V). Input impedance is 1,000 megohms for the ¡À200mV and ¡À2V inputs and 1 megohm for the ¡À20V and ¡À200V inputs. CMRR for all devices is 86dB, and inputs are overvoltage protected to ¡À250V.

Each meter incorporates an extremely stable, double-regulated reference and is fully calibrated prior to potting. We guarantee outstanding initial accuracy (¡À1 count) and excellent stability (¡À0.15 counts/¡ãC). 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 application boards that conveniently convert your meter into an application-specific instrument.
