AI6700 模拟输入模块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。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，并诅能够在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。模拟量是表示在一定范围内连续变化的任意取值 ，跟数字量是相对立的一个状态表示。通常模拟量用于采集和表示事物的电压电流或者频率等参数。模拟量输入模块是一款可以采集模拟量(如电压，电流,热电偶，热电阻，温度等数值)通过485总线传输到电脑上的智能模块。其通信协议采用MODBUS RTU协议，与工业现场数据采集实现了统一-对接， 编程起来也很方便。
The analog input module is a device that collects analog signals from remote sites to a computer. It uses the RS-485 bus as a data communication line and provides the function of converting analog signals to 485. It can simultaneously input analog signals to the module and transmit them to the computer through the RS-485 bus. Due to the use of RS-485 interface as the communication interface, it can combine multiple modules to transmit more analog signals, and can be configured dispersedly on the 485 line. It uses address codes for differentiation and can be directly connected to the MODBUS RTU protocol configuration software. An analog quantity is an arbitrary value that represents continuous changes within a certain range, and is a state representation opposite to a digital quantity. Usually, analog quantities are used to collect and represent parameters such as voltage, current, or frequency of things. The analog input module is an intelligent module that can collect analog quantities (such as voltage, current, thermocouple, thermal resistance, temperature, etc.) and transmit them to a computer through the 485 bus. Its communication protocol adopts MODBUS RTU protocol, which is unified and docked with industrial field data collection, and programming is also very convenient.
