产品描述

DS200ACNAG1A是通用电气的附加资源计算机网络板。该板以功能行业首字母缩略词 ACNA 而闻名，虽然最初是作为 Mark V EX2000 子系列的组件创建的;此外，还与 Mark VI 和 DC2000 系列产品线兼容。Mark V是GE发布的第四款用于重型涡轮机的Speedtronic燃气和蒸汽轮机管理系统，它是一种基于微处理器的三重冗余系统，由于所有关键控制和保护参数的多次备份，因此实现了极高的可靠性。EX2000 传统系列产品（如此 ACNA 模块）还往往具有直接传感器接口、内置诊断和在线维护功能。

硬件提示和规格

需要注意的是，传统的ARCNET系统（包括此DS200ACNAG1A型号）的速率为2.5 Mbps。这允许网络上的信号在大约 400 ns 内发生。这个时间限制了ARCNET系统的大小，实际上，ARCNET系统的长度不能超过四英里;如果超过这个时间，当在节点之间发送消息时，系统将开始经历延长的超时。

考虑到其非常小的电路板尺寸，DS200ACNAG1A的组件非常少。一些相关组件包括：

4 个金属膜电阻器 （R1/R2/R3/R4，）

两个晶体管，

一个二极管，

和三个电容器 （C1/C2/C3.）

Product description

The DS200ACNAG1A is an add-on resource computer network board from General Electric. The board is known by the functional industry acronym ACNA, although originally created as a component of the Mark V EX2000 subfamily; In addition, it is compatible with the Mark VI and DC2000 series product lines. The Mark V, GE's fourth Speedtronic gas and steam turbine management system for heavy-duty turbines, is a microprocessor-based triple-redundant system that achieves high reliability thanks to multiple backups of all critical control and protection parameters. EX2000 legacy products (such as ACNA modules) also tend to have direct sensor interfaces, built-in diagnostics, and in-line maintenance.

Hardware tips and specifications

It should be noted that traditional ARCNET systems (including this DS200ACNAG1A model) have a rate of 2.5 Mbps. This allows signals on the network to occur within about 400 ns. This time limits the size of the ARCNET system; in fact, the ARCNET system cannot exceed four miles in length; If this time is exceeded, the system will begin to experience extended timeouts when messages are sent between nodes.

Given its very small board size, the DS200ACNAG1A has very few components. Some relevant components include:

4 metal film resistors (R1/R2/R3/R4,)

Two transistors,

A diode,

And three capacitors (C1/C2/C3.)
