XP313电压信号输入卡是智能型带有模拟量信号调的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。
Xp313 voltage signal input card is an intelligent 6-channel analog signal acquisition card with analog signal modulation. Each channel can be separately configured and receive various types of thermocouples and voltage signals, convert them into digital signals, and send them to the main control card xp243x through data transfer card xp233.
XP313卡的6路信号理分为两组,其中1、2、3通道为一组,4、5、6通道为二组,同一组内的信号调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。XP314卡件可单独工作,也能以冗余方式工作。冗余配置时,工作卡和备用卡能对同一点信号同时进行采样和处理,可无扰动切换。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。当卡件单卡工作时,一旦自检到错误,卡件也会点亮故障灯报警。用户可通过上位机对XP313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 six channel signal processing of xp313 card is divided into two groups, of which channels 1, 2 and 3 are one group and channels 4, 5 and 6 are two groups. The signal dispatching 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. Xp314 card can work alone or in redundant mode. In redundant configuration, the working card and standby card can sample and process signals at the same point at the same time, and can switch without disturbance. 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 the card works with a single card, once an error is detected in the self-test, the card will also turn on the fault light for alarm. The user can configure the xp313 card through the upper computer to decide what signal to process, and can change it online at any time, which is convenient and flexible.
XP313在采集热电偶信号时具有冷端温度采集功能,可对一热敏电阻信号进行采集,采集范围为(-50~+50)℃之间的温室,冷端温度误差≤1℃。冷端温度的测量也可以由数据转发卡XP233完成。当组态中主控制卡对冷端设置为“就地”时,主控制卡使用I/O卡(XP314)采集的冷端温度进行信号处理,即各个热电偶信号采集卡件都各自采样冷端温度,冷端温度测量元件安装在I/O单元接线端子的底部(不可延伸),此时补偿导线一直从现场延伸到I/O单元的接线端子处;当组态中主控制卡对冷端设置为“远程”时,由数据转发卡XP233采集冷端温度进行信号处理。
Xp313 has the function of cold end temperature acquisition when collecting thermocouple signals. It can collect a thermistor signal. The acquisition range is a greenhouse between (- 50 ~ + 50) ℃, and the cold end temperature error is ≤ 1 ℃. The measurement of cold end temperature can also be completed by data transfer card xp233. When the main control card sets the cold end as "local" in the configuration, the main control card uses the cold end temperature collected by the I / O card (xp314) for signal processing, that is, each thermocouple signal acquisition card samples the cold end temperature respectively, and the cold end temperature measuring element is installed at the bottom of the I / O unit terminal (not extendable), At this time, the compensation wire extends from the field to the wiring terminal of I / O unit; When the main control card sets the cold end to "remote" in the configuration, the data is transferred to xp233 to collect the cold end temperature for signal processing.
用户可通过上位机对XP313卡进行组态,选择需要处理的信号类型,并可随时在线更改,使用方便灵活。
The user can configure the xp313 card through the upper computer, select the signal type to be processed, and change it online at any time, which is convenient and flexible.
