dcs卡件，很多人不知道为何物，其实这款产品也是在工控领域经常应用的，而且还发挥着巨大的作用，那么今天浙大中控dcs卡件XP313的小编带大家来聊聊关于dcs卡件的输入类型问题吧，下面有具体的相关介绍，希望大家都能学习下。

　　DCS card, many people do not know what it is, in fact, this product is often used in the field of industrial control, and also plays a huge role, so today, Zhejiang University central control DCS card xp313 small braid, let's talk about the input type of DCS card, the following is a specific introduction, I hope you can learn.

　　dcs卡件输入类型：

　　Input type of DCS card:

　　RTD：热电阻输入，用于连接热电阻，包括PT100、PT1000、CU50等等。TC：热电偶输入，用于连接热电阻

　　RTD: thermistor input, used to connect thermistor, including PT100, PT1000, cu50, etc. TC: Thermocouple Input, used to connect thermal resistance

　　PI：脉冲输入，用于测量脉冲输入输出类型：AO：一般为DCS给现场的阀的开度;

　　PI: pulse input, used to measure the pulse input and output type: Ao: generally refers to the opening degree of valve from DCS to the site;

　　DO：一般用于控制设备启停、电动阀的开关以及电磁阀的得失电PWM：用于输出PWM信号。

　　Do: generally used to control the start and stop of equipment, the switch of electric valve and the gain and loss of power of solenoid valve PWM: used to output PWM signal.

　　AI：模拟输入，有4-20MA电流型和0-5V电压型，一般传送现场的压力、温度、液位、流量、含量分析值

　　AI: analog input, with 4-20mA current type and 0-5V voltage type, which generally transmits the analysis values of pressure, temperature, liquid level, flow and content on site

　　DI：离散输入，有24V、220V和干接点等多种，一般用于设备的状态（启、停）、阀的反馈

　　Di: discrete input, including 24 V, 220 V and dry contact, which is generally used for the state (start and stop) of equipment and valve feedback

　　其它通讯模块：RS-232C通讯模块RS-485通讯模块以太网通讯模块各种现场总线通讯模块.

　　Other communication modules: RS-232C communication module, RS-485 communication module, Ethernet communication module, various fieldbus communication modules

　　dcs卡件按照信号类型区分，常用卡有：4~20mA输入输出、数字量输入输出（即开关量）、热电阻、热电偶、脉冲卡、通讯卡。

　　DCS cards are classified according to the signal type. The commonly used cards are: 4 ~ 20mA input and output, digital input and output (i.e. switch value), thermal resistance, thermocouple, pulse card and communication card.

　　其功能也就是将不同类型的信号转换处理。模拟量输入：AI;输出：AO；数字量输入：DI；输出：DO。

　　Its function is to convert and process different types of signals. Analog input: AI; output: Ao; digital input: Di; output: do.
