The 140CPU31110 analog input module is a device used to collect and transmit analog signals from remote sites to a computer. It uses the RS-485 bus as a data communication line and has the function of converting analog signals to 485. Through the RS-485 bus, the analog input module can transmit analog signals to the computer for processing and analysis. Analog quantity refers to any value that continuously changes within a certain range, which is opposite to digital quantity. Analog quantities are usually used to collect and represent parameters such as voltage, current, frequency, etc. of things. The analog input module can collect these analog signals and transmit them to the computer through the 485 bus. The characteristics of the analog input module include: supporting multiple modules to combine and transmit more analog signals, allowing for scattered configuration on 485 lines, and using address codes for differentiation. The configuration software that can directly connect to the MODBUS RTU protocol has achieved unified integration with industrial field data collection, and programming is also very convenient. Supports multiple acquisition ranges and can adapt to different analog signal ranges. The 140CPU31110 analog input module is widely used in industrial automation, environmental monitoring, energy management and other fields, providing important support for data acquisition and monitoring systems.
