140ACI03000C 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.

140ACI03000C analog quantity is an arbitrary value that indicates continuous change within a certain range, and is a state representation opposite to the digital quantity. Analog quantities are usually used to capture and represent parameters such as voltage, current or frequency of things. Analog input module can collect analog values (such as voltage, current, thermocouple, thermal resistance, temperature, etc.) and transmit to the computer through the 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.
