DMS-30PC-3-VFS-C工业自动化与控制的面板仪表规格书PDF中文资料

DMS-30PC-3-VFS-C属于工业自动化与控制的面板仪表。由村田制作所制造生产的DMS-30PC-3-VFS-C面板仪表面板仪表是使用模拟指针或其他物理指示器或数字字符以可视方式显示输入信号的仪器。许多面板仪表还包括可用于报警选项的辅助输出，以及将数据或参考信号传输到计算机或微控制器的功能。面板仪表可根据测量范围、显示类型、字符/指示器属性和供电电压进行选择。仪表类型包括电流、电压、频率、过程、电阻、温度和功率。

The DMS-30PC Series is a broad line of self-contained, fully operational, 3½ 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 (±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/°C). 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.
