Description

The DMS-30PC Series is a broad line of self-contained, fully operational, 31/2 digit voltmeters 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 and 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.

DMS-30PCs 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/).  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 thermocouples, etc.), the DMS-30PC Series includes a complete line of optional "plug-on" application boards that conveniently convert your meter into an applica- tion-specific instrument.
