模拟量输入模块是一款将远程现场的模拟量信号采集至计算机的设备，10QT01其利用RS-485总线作为数据通信线路，提供模拟量转485功能，能够同时将八路模拟量输入至模块，并通过RS-485总线传输至计算机。由于采用RS-485接口作为通信接口，其能够多个模块组合传输更多路数模拟量信号，并且能够在485线路上分散配置，采用地址码进行区分，可以直接接入MODBUS RTU协议的组态软件。

模拟量输入模块是一种用于采集模拟信号的电子模块，其工作原理如下：

模拟量输入模块通过接收来自现场的模拟信号，10QT01信号可以是电压、电流、温度、压力等连续变化的物理量。在模块内部，这些模拟信号经过预处理电路进行滤波、放大、隔离等操作，以减小噪声和干扰对信号的影响。

然后，10QT01模拟量输入模块将模拟信号转换为数字信号。这个过程通常使用模数转换器（ADC）进行，将模拟信号按照一定的采样频率和精度进行采样，并将每个采样点的幅值用二进制数字表示。采样的精度和范围决定了模块能够表示的模拟信号的范围和精度。

最后，数字信号被传输到计算机系统中进行处理和分析。10QT01过程可以通过多种方式实现，如通过串行或并行接口将数据传输到计算机的内存中，或者通过现场总线系统将数据传输到计算机的处理器中进行进一步的处理。

总之，模拟量输入模块通过将现场的模拟信号转换为数字信号，并传输到计算机系统中进行处理和分析，实现了对模拟量的采集、处理和监测等功能。其工作原理涉及到模拟信号的预处理、模数转换和数字信号的传输等多个环节，是实现工业自动化和智能化的重要组成部分之一。

Analog input module is a device that collects analog signals from remote field to computer. 10QT01 uses RS-485 bus as a data communication line to provide analog to 485 function, which can simultaneously input eight analog signals to the module and transmit them to the computer through RS-485 bus. As the RS-485 interface is used as the communication interface, it can combine multiple modules to transmit more analog signals, and can be distributed on the 485 line, using the address code to distinguish, and can directly access the configuration software of MODBUS RTU protocol.

Analog input module is an electronic module used to collect analog signals, and its working principle is as follows:

Analog input module by receiving the analog signal from the field, 10QT01 signal can be a continuous change of voltage, current, temperature, pressure and other physical quantities. In the module, these analog signals are filtered, amplified and isolated by the pre-processing circuit to reduce the impact of noise and interference on the signal.

The 10QT01 analog input module then converts the analog signal into a digital signal. This process is usually performed using an analog-to-digital converter (ADC), which samples the analog signal at a certain sampling frequency and precision, and the amplitude of each sampling point is represented by a binary digit. The accuracy and range of sampling determines the range and accuracy of the analog signal that the module can represent.

Finally, the digital signal is transmitted to a computer system for processing and analysis. The 10QT01 process can be implemented in a variety of ways, such as transferring data to the computer’s memory via a serial or parallel interface, or transferring data to the computer’s processor for further processing via a fieldbus system.

In a word, the analog input module converts the analog signal into digital signal and transmits it to the computer system for processing and analysis, and realizes the functions of acquisition, processing and monitoring of the analog signal. Its working principle involves the pre-processing of analog signals, analog-to-digital conversion and transmission of digital signals, and is one of the important components of industrial automation and intelligence.
