XP313是一块带CPU的智能型卡件,对模拟量电流输入信号进行调理、测量的同时,还具备卡件自检及与主控制卡通讯的功能。为了更好顺利的使用,下面来重新了解下它吧。
Xp313 is an intelligent card with CPU, which not only regulates and measures the analog current input signal, but also has the functions of card self-test and communication with the main control card. For better and smooth use, let's re understand it.
XP313卡的6路信号,电源及信号互相隔离,并且都与控制站的电源隔离。当卡件被拔出时,卡件与主控制卡通讯中断,系统监控软件显示此卡件通讯故障。XP313卡的每一路可分别接收=2ROMANII型或=3ROMANIII型标准电流信号。当需XP313卡向变送器配电时可通过DC/DC对外提供6路+24V的隔离电源,每一路都可以通过跳线选择是否需要配电功能。
The six channel signals, power supply and signals of xp313 card are isolated from each other, and are all isolated from the power supply of the control station. When the card is pulled out, the communication between the card and the main control card is interrupted, and the system monitoring software displays the communication failure of the card. Each channel of xp313 card can receive =2romanii or =3romaniii standard current signals respectively. When the xp313 card is required to distribute power to the transmitter, 6 channels of +24v isolated power supply can be provided externally through DC / DC, and each channel can be used to select whether the power distribution function is required through jumpers.
XP313卡件是浙大中控JX-300Xp系统中一种基本卡件,是6路电流输入卡,可连接压力变送器,流量计,液位计,变频器的电流反馈等4-20ma输入的各类设备,可以有源和无源两种信号输入类型,若是单卡配置的系统,xp313卡件坏掉后,与之相连的六路信号就不能显示了,组态编程中与之相关的程序也就不能起到作用了。
Xp313 card is a basic card in the JX-300XP system of Zheda central control. It is a 6-way current input card, which can be connected to various 4-20mA input devices such as pressure transmitter, flowmeter, liquid level gauge, current feedback of frequency converter, etc. it can have active and passive signal input types. If it is a single card configuration system, after the xp313 card is broken, the 6-way signals connected to it cannot be displayed, The program related to configuration programming will not work.

一般情况下,卡件都是在单卡状态下运行,重要场合采用冗余配置,单卡配置时,J1/J2/J3/J4/J5/J6/J7/J8,1-2短接,冗余配置时,J1/J2/J3/J4/J5/J6/J7/J8,2-3短接。
Generally, the cards operate in the single card state, and redundant configuration is adopted in important occasions. In the single card configuration, j1/j2/j3/j4/j5/j6/j7/j8, 1-2 short circuit, and in the redundant configuration, j1/j2/j3/j4/j5/j6/j7/j8, 2-3 short circuit.
当外界仪表需要DCS系统供电时,如压力变送器,涡街流量计,差压变送器等一般是配电的,JP1JP2JP3JP4JP4JP5JP6的1-2短接,不需要配电时,如电磁流量计,质量流量计,JP1JP2JP3JP4JP4JP5JP6就是2-3短接,注意JP8是保护跳线,不能随意短接。
When external instruments need DCS system power supply, such as pressure transmitter, vortex flowmeter, differential pressure transmitter, etc., they are generally power distribution. Jp1jp2jp3jp4jp4jp5jp6 is short circuited from 1-2. When power distribution is not required, such as electromagnetic flowmeter, mass flowmeter, jp1jp2jp3jp4jp4jp5jp6 is short circuited from 2-3. Note that JP8 is a protective jumper and cannot be short circuited at will.
当负载电阻较小时,电压会降低,一般18-24伏都是正常范围,尽量不要现场仪表不要短路,卡件控制的短路电流一般不会高于24ma,对现场起到安全保护的作用。
When the load resistance is small, the voltage will decrease. Generally, 18-24 volts are in the normal range. Try not to short circuit the field instrument. The short-circuit current controlled by the card is generally not higher than 24Ma, which plays a role of safety protection on the site.
浙大中控dcs卡件XP313对应的端子板是通用的端子板,XP520,其接线是12、34、56、910、11121314.注意当外电路输入电流时,就是外供电时,正负极要反接,总体原则就是偶数端子是电流进入的端子,无论是配电还是不配电。
The terminal board corresponding to Zheda central control DCS card xp313 is a general terminal board, xp520, and its wiring is 12, 34, 56, 910, 11121314. Note that when the external circuit input current, that is, the external power supply, the positive and negative electrodes should be reversed. The general principle is that the even number of terminals is the terminal of current entry, whether it is power distribution or not.
