              浙大DCS中控卡件信號傳輸卡介紹!

              XP314電壓信號輸入卡是智能型帶有模擬量信號調理的6路模擬信號采集卡,每一路可單獨組態并接收各種型號的熱電偶以及電壓信號,將其調理后再轉換成數字信號并通過數據轉發卡XP233送給主控制卡XP243X。
              Xp314 voltage signal input card is an intelligent 6-channel analog signal acquisition card with analog signal conditioning. Each channel can be separately configured and receive various types of thermocouples and voltage signals, convert them into digital signals after conditioning, and send them to the main control card xp243x through data transfer card xp233.
              XP314卡的6路信號調理分為兩組,其中1、2、3通道為組,4、5、6通道為二組,同一組內的信號調理采用同一個隔離電源供電,兩組之間的電源和信號互相隔離,并且都與控制站的電源隔離??蓡为毠ぷ?,也能以冗余方式工作??哂凶栽\斷功能,在采樣、處理信號的同時,也在進行自檢??哂嗯渲脮r,一旦工作卡自檢到故障,立即將工作權讓給備用卡,并且點亮故障燈報警,等待處理。工作卡和備用卡對同一點信號同時進行采樣和處理,無擾動切換。單卡工作時,一旦自檢到錯誤,卡件也會點亮故障燈報警。
              The six channel signal conditioning of xp314 card is divided into two groups, of which channels 1, 2 and 3 are groups and channels 4, 5 and 6 are two groups. The signal conditioning in the same group is powered by the same isolated power supply. The power supply and signals between the two groups are isolated from each other and are isolated from the power supply of the control station. The card can work alone or in a redundant manner. The card has the function of self diagnosis. While sampling and processing signals, it is also performing self inspection. During card redundancy configuration, once the work card detects a fault, it will immediately give the work right to the standby card, and light the fault light to alarm and wait for processing. The working card and the standby card sample and process the signals at the same point at the same time, and switch without disturbance. When a single card works, once an error is detected, the card will also turn on the fault light for alarm.
              用戶可通過上位機對XP314卡進行組態,決定其對何種信號進行處理,并可隨時在線更改,使用方便靈活。
              The user can configure the xp314 card through the upper computer to decide what signal to process, and can change it online at any time, which is convenient and flexible.
