ACC-28E 模數(shù)轉(zhuǎn)換器

配置:
?選項(xiàng)1:附加兩個(gè)板載16位A/D轉(zhuǎn)換器
?選項(xiàng)2B:安裝子卡

部件編號(hào):603404-105

特點(diǎn):
2或4通道
模數(shù)轉(zhuǎn)換器
精密電壓測(cè)量
Delta Tau ACC-28E高分辨率a – d轉(zhuǎn)換器是一款2或4通道(可選1)模擬到數(shù)字轉(zhuǎn)換器接口板，旨在提供一種精密電壓測(cè)量手段，作為UMAC Turbo或UMAC MACRO系統(tǒng)的輸入。該配件使用四個(gè)(或兩個(gè))16位模擬到數(shù)字轉(zhuǎn)換器，提供精確到±2位的電壓測(cè)量。

跳線允許每個(gè)A-D轉(zhuǎn)換器被選擇為雙極或單極轉(zhuǎn)換模式。當(dāng)選擇雙極模式時(shí)，差分輸入允許用戶將輸入電壓施加到±10伏(20V p-p)。當(dāng)選擇單極模式時(shí)，用戶可以應(yīng)用從0V到+10V的輸入電壓(負(fù)輸入必須接地)。

為比率式輸入控制提供了電壓參考。VREF輸出是為使用縮放輸入進(jìn)行精確跟蹤的設(shè)備提供的。+5Vdc和-5Vdc電源抽頭不太精確，并且提供允許用戶在不需要外部電源的情況下偏置電位器。

提供輸入零修剪器以允許輸入信號(hào)的精確調(diào)整。光耦合器用于隔離ac – 28e的電路與PMAC。

Acc-28E將部署在Delta Tau的3U機(jī)架上。背板提供ac – 28e所需的所有電源(±15Vdc， +5Vdc)。然而，與卡上的一些跳線相關(guān)聯(lián)的終端塊也允許用戶連接外部±15Vdc，如果他們選擇這樣做的話。

ACC-28E 模數(shù)轉(zhuǎn)換器

Configuration:
? Option 1: Additional two on-board 16-bit A/D converters
? Option 2B: Installed daughter card

Part Number: 603404-105

Features:
2 or 4 Channel
Analog to Digital Converter
Precision Voltage Measurement
The Delta Tau ACC-28E High Resolution A-D Converter is a 2 or 4 (Option 1) channel analog to digital converter interface board designed to provide a means for precision voltage measurement as an input to the UMAC Turbo or UMAC MACRO systems. This accessory uses four (or two) 16-bit analog to digital converters to provide voltage measurements accurate to ±2 bits.

Jumpers allow each A-D converter to be selected for bipolar or unipolar convert modes. When selected for bipolar mode, differential inputs allow the user to apply input voltages to ±10 volts (20V p-p). When selected for unipolar mode, the user can apply input voltages from 0V to +10V (the negative input must be grounded).

Voltage references are provided for ratiometric style input control. The VREF output is provided for equipment that uses a scaled input for accurate tracking. The +5Vdc and -5Vdc supply taps are less precise, and are provided to allow the user to bias potentiometers without the need for an external power supply.

Input nulling trimmers are provided to allow for precise adjustment of input signals. Opto-couplers are used to isolate the Acc-28E’s circuitry from the PMAC.

Acc-28E will be located in Delta Tau’s 3U rack. The backplane provides all the power needed (±15Vdc, +5Vdc) for the Acc-28E. However, a terminal block associated with some jumpers on the card also allows the user to connect external ±15Vdc if they chose to do so.
