IS200VSVOH1B? 在前面板上的 J5 插頭和 VME 機(jī)架上的 J3/J4 連接器上
IS200VSVOH1B 是通用電氣制造的 VME 伺服控制板,屬于燃?xì)廨啓C(jī)控制系統(tǒng)中使用的 Mark VI 系列的一部分。操作蒸汽/燃料閥的四個(gè)電液伺服閥在伺服控制 (VSVO) 板的指導(dǎo)下。通常,使用兩個(gè)伺服端子板來(lái)分隔這四個(gè)通道(TSVO 或 DSVO)。使用線性可變差動(dòng)變壓器確定閥門(mén)位置 (LVDT)。
VSVO 執(zhí)行環(huán)路控制算法。在前面板上的 J5 插頭和 VME 機(jī)架上的 J3/J4 連接器上,三根電纜連接到 VSVO。JR1 連接器用于
TSVO 提供單工信號(hào),而 JR1、JS1 和 JT1 連接器用于扇出 TMR 信號(hào)。將保護(hù)模塊的外部跳閘插入 JD1 或 JD2。
IS200VSVOH1B安裝
關(guān)閉 VME 的處理器機(jī)架。
將板放置到位,然后用手將頂部和底部控制桿按入邊緣連接器的底座中。
擰緊前面板頂部和底部的自攻螺釘。
與 TSVO 端子板的電纜連接通過(guò) VME 機(jī)架上下部的 J3 和 J4 連接器進(jìn)行。為了固定電纜,它們采用閉鎖連接。啟動(dòng) VME 機(jī)架并查看前面板上的診斷指示燈。
IS200VSVOH1B操作
LVDT 位置反饋、LVDT 激勵(lì)、雙向伺服電流輸出和脈沖率流量輸入均包含在 VSVO 的四個(gè)通道中。
TSVO 最多可以提供六個(gè) LVDT 閥位輸入的激勵(lì),TSVO 也接受來(lái)自這些輸入的輸入。對(duì)于每個(gè)伺服控制環(huán)路,可以選擇一個(gè)、兩個(gè)、三個(gè)或四個(gè) LVDT。
對(duì)于測(cè)量燃?xì)廨啓C(jī)流量的應(yīng)用,提供了三個(gè)輸入。這些信號(hào)通過(guò) TSVO 并直接發(fā)送到 VSVO 板正面的 J5。斷電時(shí),每個(gè)伺服輸出都有一個(gè)專(zhuān)用自殺繼電器,在由固件控制時(shí),會(huì)將 VSVO 輸出信號(hào)短接到公共信號(hào),然后根據(jù)手動(dòng)復(fù)位指令返回正常操作。
每個(gè)伺服系統(tǒng)的輸出電壓、電流和自殺繼電器均通過(guò)診斷進(jìn)行監(jiān)控。

A Discrete Input/Output Board is a circuit board that contains discrete input and output ports for connecting external devices. These ports can be digital or analog and can be used to connect various devices, such as sensors, actuators, switches, buttons, etc.
Discrete input/output boards usually include a microcontroller or microprocessor that processes input and output signals and performs corresponding control operations. These boards usually also include a number of input and output circuits, such as digital input/output ports, analog input/output ports, counters, timers, etc.
Discrete input/output boards are commonly used in industrial automation, robotics, data acquisition, control systems and other applications, where they provide a convenient way to connect external devices and enable control and monitoring of these devices.
A discrete input/output board is a circuit board that processes the input and output signals separately. Such boards usually contain multiple input ports and output ports for connecting different devices or systems.
The advantage of discrete input/output boards is that input and output signals can be flexibly configured to meet different application requirements. For example, input signals can be connected to different sensors or data sources and output signals to different actuators or devices. This circuit board can be applied to various fields, such as industrial automation, smart home, automotive electronics, etc.
When using discrete input/output boards, you need to configure and expand them based on actual requirements. At the same time, it is necessary to pay attention to the accuracy and real-time performance of the signal to ensure the stability and reliability of the system.
