　　规格

　　零件编号：IS230PCAAH1A

　　制造商：通用电气

　　制造国：美国产品

　　类型：核心模拟模块

　　尺寸： 17.71 × 13.77 × 7.87 厘米

　　工作温度：-30 至 65 摄氏度

　　系列： Mark VIe

　　IS230PCAAH1A是专为Mark VIe系统设计的内核模拟模块。它由通用电气开发。运行燃气轮机所需的大部分模拟信号 I/O 由核心模拟 (PCAA) 模块和相关核心模拟(TCAS 和 TCAT)终端板提供。热电偶输入、4-20 mA 电流环路 I/O、地震输入、线性可变差分变压器 (LVDT) 激励和输入、脉率输入和伺服线圈输出均由 PCAA 和 TCAT 提供。

　　功能描述

　　该模块适用于单工、双工和 TMR 系统。单个TCAT终端板将信号输入分配到一个、两个或三个PCAA模块。

　　相邻的JGPA板的屏蔽接地和24 V现场电源端子补充了PCAA和TCAT上的端子。模块包括一个由所有 Mark VIe 分布式 I/O 板共享的处理器板、两个应用 I/O 板和一个终端板。

　　整个模块被视为最不可更换的单元，并且不提供任何帮助来诊断或更换组成模块的单个电路板。

　　该模块由一个 28 V 直流电源连接器和两个 RJ45 以太网连接器供电。在模块的边缘，120 个欧式盒式端子提供现场设备 I/O，通过连接器 P4 为 JGPA 板供电。该模块通过连接器 P1 和 P2 上的两根 68 针电缆连接到 TCAT。

　　PCAA信号分为两组。TCAT端子板将信号输入路由到单个、双通道或TMR PCAA模块。专用于单个PCAA模块的信号连接到端子。如果不需要扇形输入，则可以在没有 TCAT 的情况下使用 PCAA。

　　The IS230PCAAH1A is a kernel simulation module designed for Mark VIe systems. It was developed by General Electric. Most of the analog signal I/O required to operate a gas turbine is provided by the Core Analog (PCAA) module and the associated core analog (TCAS and TCAT) terminal boards. Thermocouple input, 4-20 mA current loop I/O, seismic input, linear Variable differential transformer (LVDT) excitation and input, pulse rate input, and servo coil output are all provided by PCAA and TCAT.

　　Function description

　　The module is suitable for simplex, duplex and TMR systems. A single TCAT terminal board distributes signal inputs to one, two, or three PCAA modules.

　　The shielded ground of the adjacent JGPA board and the 24 V field power terminals complement the terminals on the PCAA and TCAT. The module consists of a processor board shared by all Mark VIe distributed I/O boards, two application I/O boards, and a terminal board.

　　The entire module is considered the least replaceable unit, and no help is provided to diagnose or replace the individual circuit boards that make up the module.

　　The module is powered by a 28 V DC power connector and two RJ45 Ethernet connectors. At the edge of the module, 120 European box terminals provide field device I/O and power the JGPA board via connector P4. The module is connected to the TCAT via two 68-pin cables on connectors P1 and P2.

　　PCAA signals are divided into two groups. The TCAT terminal board routes the signal input to a single, two-channel, or TMR PCAA module. Signals dedicated to individual PCAA modules are connected to terminals. If sector input is not required, PCAA can be used without TCAT.
