7AI261.7 Analog input module is a device that collects analog signals from remote field to computer, and 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.
7AI261.7 Because of the use of RS-485 interface as a communication interface, it can combine multiple modules to transmit more analog signals, and can be dispersed on the 485 line, using the address code to distinguish, can directly access the MODBUS RTU protocol configuration software.
7AI261.7 The analog quantity is an arbitrary value that indicates continuous change within a certain range, and is a state representation that is opposed to the digital quantity.
Analog quantities are usually used to capture and represent parameters such as voltage, current or frequency of things. 7AI261.7 Analog input module is an intelligent module that can collect analog values (such as voltage, current, thermocouple, thermal resistance, temperature, etc.) and transmit them to the computer through the 485 bus. The communication protocol adopts MODBUS RTU protocol, which realizes the unified docking with the industrial field data acquisition, and the programming is also very convenient.
