GE DS3800NADC1D1D 用作模拟输入卡

产品描述

GE制造了DS3800NADC1D1D，用作模拟输入卡，作为其Mark IV系统中的组件。Mark IV专为燃气轮机和蒸汽轮机控制而设计，基于“有意冗余”理论。它具有集成的芯片组，可以部分复制彼此的职责，从而可以将责任从故障PCB转移到工作板上，以保持整个系统的正常运行。

DS3800NADC1D1D在其上边缘标记为对齐。它有四个单独标记的测试点（TP）。一个接线端子（7 x 4）位于电路板中心附近。公连接器位于电路板的左侧，允许与其他 PCB 通信。

DS3800NADC1D1D包括多个电阻器和集成电路。 其中一个电路是位于右上象限的Datel A/D转换器。附近有两个微调电位器，用于转换器芯片的零点或偏移和增益的外部调整。它们尽可能靠近在一起，以避免噪音拾取。DATEL 芯片具有短周期操作、内部高 z 输入缓冲器和 8 或 20 微秒转换时间。它具有12位分辨率。

Product description

GE manufactured the DS3800NADC1D1D to be used as an analog input card as a component in its Mark IV system. The Mark IV is designed for gas and steam turbine control and is based on the theory of "intentional redundancy". It has an integrated chipset that partially replicates each other's responsibilities, allowing responsibility to be transferred from the faulty PCB to the work board to keep the entire system up and running.

DS3800NADC1D1D is marked aligned on its top edge. It has four individually labeled test points (TPS). One terminal (7 x 4) is located near the center of the board. The male connector is located on the left side of the board, allowing communication with other PCBS.

The DS3800NADC1D1D includes multiple resistors and integrated circuits. One of these circuits is the Datel A/D converter located in the upper right quadrant. Nearby are two trimmer potentiometers for external adjustment of the zero or offset and gain of the converter chip. They are as close together as possible to avoid noise picking. The DATEL chip has short-cycle operation, an internal high-Z input buffer, and 8 or 20 microsecond conversion times. It has a 12-bit resolution.
