ABB AI625 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, 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。

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 eight 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 485 lines. It uses address codes for differentiation and can be directly connected to the MODBUS RTU protocol configuration software.
