YS1700-100/A06/A31 主要以微处理器为计算和控制核心

单回路控制仪，也被称为单回路控制器或单回路数字控制器，YS1700-100/A06/A31 是一种数字式控制仪表。它主要以微处理器为计算和控制核心，并配备相应的软件。在外观和使用上，它与常规的模拟控制器相似。

单回路控制仪具有多个功能。首先，它可以接收多个输入信号，但只输出一个模拟量信号，从而构成单回路直接数字控制。其次，它通常由微处理器、过程输入输出通道、正面板、侧面板、供电电源、数字通信系统等硬件部分，以及监控系统、基本算式编程系统等软件部分组成。这使得用户可以根据需要编制程序，组成各种调节规律，因此它也被称为“可编程控制器”。

此外，单回路控制由四个基本环节组成，即被控对象（或过程）、测量变送装置、控制器和控制阀。单回路控制器的主要任务是对控制系统的整定。对于已经设计并安装好的控制系统，通过调整控制器的参数，可以使系统的过渡过程达到满意的质量指标要求。

单回路控制器具有两个控制回路：比例积分模拟回路和比例积分温度控制回路。这种控制器特别适用于单回路的简单控制系统与复杂的串级控制系统。除了能完成传统的模拟控制器的比例、积分、微分控制功能外，YS1700-100/A06/A31 还能进行加、减、乘、除、开方等运算，以及进行高、低值选择和逻辑运算等。

Single loop controller, also known as single loop controller or single loop digital controller, YS1700-100/A06/A31 is a digital control instrument. It mainly takes the microprocessor as the core of calculation and control, and is equipped with corresponding software. In appearance and use, it is similar to a conventional analog controller.

The single loop controller has multiple functions. First, it can receive multiple input signals, but only output an analog signal, thus constituting a single loop direct digital control. Secondly, it is usually composed of a microprocessor, a process input and output channel, a front panel, a side panel, a power supply, a digital communication system and other hardware parts, as well as a monitoring system, a basic computational programming system and other software parts. This allows users to prepare programs according to their needs and compose various adjustment laws, so it is also called a “programmable controller”.

In addition, single-loop control consists of four basic links, namely, the controlled object (or process), the measurement transmission device, the controller and the control valve. The main task of the single loop controller is to adjust the control system. For the designed and installed control system, by adjusting the parameters of the controller, the transition process of the system can reach the satisfactory quality index requirements.

The single-loop controller has two control loops: a proportional integral analog loop and a proportional integral temperature control loop. This kind of controller is especially suitable for simple single-loop control system and complex cascade control system. In addition to the proportion, integral and differential control functions of the traditional analog controller, YS1700-100/A06/A31 can also be added, subtraction, multiplication, division, root and other operations, as well as high and low value selection and logical operations.
