产品描述

DS3800NADC1C1A是GE的PCB，设计用作Mark IV系统中的模拟输入电路卡。Mark IV 专为蒸汽和燃气轮机控制管理而设计。Mark IV可用于自动化涡轮机系统的几乎所有方面。

DS3800NADC1C1A的每个角落都有工厂钻孔。它被标记为（A 到 J）以在一条边上对齐。提取夹已连接到两个角。 这些允许技术人员在不接触电路的情况下插入或拔出 PCB.它还允许更容易地放置在狭窄的位置。

DS3800NADC1C1A沿一条边放置了四个测试点。这些是单独标记的。一个接线端子放置在电路板右上方附近。公连接器填充电路板的整个左边缘。这允许DS3800NADC1C1A与其他 PCB 通信.

两个微调电位计并排放置在右边缘。它们用于 DATEL A/D 转换器的零点或偏移和增益的外部调整。电路板上填充多个电阻器，通常由陶瓷覆盖的金属膜组成。该板具有 33 个集成电路，包括一个 DATEL A/D 转换器，该转换器具有 5 个输入电压范围和 12 位分辨率。它包括一个时钟、一个单芯片12位连续近似寄存器和一个单芯片缓冲放大器。非线性度指定为+/- 1/2 LSB最大值。

Product description

The DS3800NADC1C1A is a GE PCB designed to be used as an analog input circuit card in Mark IV systems. The Mark IV is designed for steam and gas turbine control management. The Mark IV can be used to automate almost all aspects of turbine systems.

The DS3800NADC1C1A has factory holes in every corner. It is labeled (A to J) to align on one edge. The extraction clip has been attached to both corners. These allow the technician to insert or remove the PCB without touching the circuit. It also allows for easier placement in narrow locations.

The DS3800NADC1C1A places four test points along an edge. These are labeled separately. One terminal is placed near the top right of the board. The male connector fills the entire left edge of the board. This allows the DS3800NADC1C1A to communicate with other PCBS.

Two trimmer potentiometers are placed side by side on the right edge. They are used for external adjustment of zero or offset and gain of DATEL A/D converters. The circuit board is filled with multiple resistors, usually consisting of a metal film covered with ceramic. The board features 33 integrated circuits, including A DATEL A/D converter with 5 input voltage ranges and 12-bit resolution. It consists of a clock, a single-chip 12-bit continuous approximation register, and a single-chip buffer amplifier. The nonlinearity is specified as +/ -1/2 LSB maximum.
