The DMS-30PC Series is a wide line of self-contained, fully operational, 3½ digit voltmeters with large, easy-to-read LED displays.
The DATEL DMS-30PC Series consists of self-contained, fully operational 3½ digit voltmeters with large, easy-to-read LED displays. These devices integrate the display, drivers, reference circuit, and A/D converter into a single, epoxy-encapsulated 12-pin DIP package that is vibration and moisture proof. The meters are available in various LED colors and low-power options, suitable for panel or PC card mounting.
