DMS-EB2

Multi-Purpose Application Board

for DMS-20PC/LCD Meters

MPM_DMS-EB2.E01 Page 1 of 4

The DMS-EB2 Application Board was designed for quick and easy application/evalu-

ation of DATEL's subminiature DMS-20PC/LCD Series, 3½ Digit, LED/LCD Display, Digital

Panel Voltmeters. The DMS-EB2's versatility, low cost and direct DMS-20PC/LCD plug-in

compatibility makes interfacing a breeze. The DMS-EB2 covers many common panel-

meter applications while providing easy signal and power I/O terminations (via a standard

MOLEX connector) and plug-in versatility when changing from one application to another.

The DMS-EB2 has provisions for such common applications as input dividers for high

input voltages, gain (span) adjustment, 9/12Vdc battery operation, and decimal point place-

ment. The board permits direct signal I/O wiring via the interface connector or soldering

directly to the board. The DMS-EB2 is fully compatible with all four versions of the DMS-

20PC/LCD (±200mV, ±2V, ±20V, ±200V) making it interchangeable from meter to meter

and application to application. Solder gaps

are conveniently placed on the board and

may be quickly bridged or cut as required.

This low-cost addition to DATEL's

expanding line of subminiature meters dem-

onstrates our continuing commitment to offer

the most versatile, easy-to-use panel-meter

products.
