140ARI03010C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，其利用RS-485总线作为数据通信线路，提供模拟量转485功能，能够同时将模拟量输入至模块，并通过RS-485总线传输至计算机。

此外，140ARI03010C模拟量输入模块也常见于PLC（可编程逻辑控制器）中。PLC模拟量输入模块接收的输入信号为连续的模拟信号，信号值可以在一定范围内连续变化，通常表示物理量的大小，如温度、压力等。PLC模拟量输入模块对输入信号进行模数转换，将连续的模拟信号转换为数字信号表示，具有较高的精度和分辨率，可以精确地测量模拟信号的大小。这种模块通常具有较少的输入通道，每个通道接收一个模拟信号，因为每个模拟信号需要更多的资源进行处理。

140ARI03010C模拟量扩展模块中，模拟量类型的模块有三种：普通模拟量模块、RTD模块和TC模块。普通模拟量模块可以采集标准电流和电压信号，电流包括0-20mA、4-20mA两种信号，电压包括+/-2.5V等。

140ARI03010C analog input module is a device that collects analog signals from remote field to computer, which uses RS-485 bus as a data communication line to provide analog to 485 function, which can simultaneously input analog to the module and transmit it to the computer through RS-485 bus.

In addition, the 140ARI03010C analog input module is also commonly found in PLC (Programmable logic Controller). The input signal received by the PLC analog input module is a continuous analog signal, and the signal value can be continuously changed within a certain range, usually indicating the size of the physical quantity, such as temperature, pressure, etc. The PLC analog input module converts the input signal to digital, converts the continuous analog signal to digital signal representation, has high accuracy and resolution, and can accurately measure the size of the analog signal. Such modules typically have fewer input channels, each receiving one analog signal, because each analog signal requires more resources to process.

In the 140ARI03010C analog expansion module, there are three types of analog modules: ordinary analog module, RTD module and TC module. Ordinary analog module can collect standard current and voltage signals, current includes 0-20mA, 4-20mA two kinds of signals, voltage includes +/-2.5V and so on.
