GE DS3800NFCF1F1D 晶体振荡器和一个 8 位静态 MOS RAM 芯片

产品描述

DS3800NFCF1F1D是GE用于Mark IV / Speedtronic系列的PCB。Mark IV 是为燃气轮机/蒸汽轮机管理而创建的，有助于将汽轮机系统保持在安全运行参数范围内。它还可以自动执行某些过程，包括关闭和启动。

DS3800NFCF1F1D由42个电路组成。这包括设置为 11.000 MHz 的晶体振荡器和一个 8 位静态 MOS RAM 芯片，该芯片具有组织为 2 x 256 的 8K 位静态单元。它的zui短访问时间为 400ns，允许在 8085AH CPU 中使用，无需等待状态。该板还具有同步 4 位上/下计数器，该计数器具有内部提供的级联电路和每个触发器的单独预设。

该DS3800NFCF1F1D有 10 个 LED、218 个晶体管、4637 个测试点和 4 个跳线。它还具有三个用于与其他板通信的连接器，包括一个 <> 针垂直连接器和两个 <>A<>-P<> 连接器。该板由多个电容器、二极管和电阻器构成。

DS3800NFCF1F1D可以充当较小DS3800DFCF的主板。 当存在DS3800DFCF时，较大的电路板可以访问更多组件，包括电流表和跳线开关。DS3800NFCF1F1D左侧的四个尼龙销用于支撑辅助装置的角落。该板由 <> 个板对板引脚固定到位。

安装和维护指南可在DS3800NFCF1F1D的数据表和手册中找到。技术支持出版物由GE分发。

Product description

The DS3800NFCF1F1D is GE's PCB for the Mark IV/Speedtronic series. The Mark IV was created for gas turbine/steam turbine management to help keep turbine systems within safe operating parameters. It can also automate certain processes, including shutdown and startup.

The DS3800NFCF1F1D consists of 42 circuits. This includes a crystal oscillator set to 11.000 MHz and an 8-bit static MOS RAM chip with 8K-bit static cells organized at 2 x 256. It has a minimum access time of 400ns and is allowed to be used in 8085AH cpus without the wait state. The board also features a synchronous 4-bit up/down counter with an internally supplied cascade circuit and separate presets for each trigger.

The DS3800NFCF1F1D has 10 leds, 218 transistors, 4,637 test points, and 4 jumpers. It also has three connectors for communicating with other boards, including A<> pin vertical connector and two <>A<>-P<> connectors. The board consists of a plurality of capacitors, diodes and resistors.

The DS3800NFCF1F1D can act as a motherboard for the smaller DS3800DFCF. When the DS3800DFCF is present, larger boards have access to more components, including ammeters and jumper switches. The four nylon pins on the left side of the DS3800NFCF1F1D are used to support the corners of the auxiliary. The board is held in place by <> board-to-board pins.

Installation and maintenance instructions can be found in the data sheets and manuals of the DS3800NFCF1F1D. Technical support publications are distributed by GE.
