140DVO85300C输入输出模块

模拟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。

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

The analog input module is a device that collects the analog signal from the remote field to the computer. It uses the RS-485 bus as a data communication line and provides the analog to 485 function, which can input the analog signal to the module at the same time and transmit it to the computer through the 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
