XP314电压信号输入卡是智能型带有模拟量信号调理的6路模拟信号采集卡,每一路可单独组态并接收各种型号的热电偶以及电压信号,将其调理后再转换成数字信号并通过数据转发卡XP233送给主控制卡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路信号调理分为两组,其中1、2、3通道为组,4、5、6通道为二组,同一组内的信号调理采用同一个隔离电源供电,两组之间的电源和信号互相隔离,并且都与控制站的电源隔离。卡件可单独工作,也能以冗余方式工作。卡件具有自诊断功能,在采样、处理信号的同时,也在进行自检。卡件冗余配置时,一旦工作卡自检到故障,立即将工作权让给备用卡,并且点亮故障灯报警,等待处理。工作卡和备用卡对同一点信号同时进行采样和处理,无扰动切换。单卡工作时,一旦自检到错误,卡件也会点亮故障灯报警。
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.
用户可通过上位机对XP314卡进行组态,决定其对何种信号进行处理,并可随时在线更改,使用方便灵活。
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.
