DMS-EB2工业自动化与控制的面板仪表-配件规格书PDF中文资料

The DMS-EB2 Application Board was designed for quick and easy application/evaluation of DATELs subminiature DMS-20PC/LCD Series, 3½ Digit, LED/LCD Display, Digital Panel Voltmeters. The DMS-EB2s 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 DATELs expanding line of subminiature meters demonstrates our continuing commitment to offer the most versatile, easy-to-use panel-meter products.
