Working principle

The working principle of the 140DDI84100 module mainly includes four steps:signal acquisition,signal conditioning,A/D conversion and data transmission

Signal acquisition:The module receives the analog signal generated by the field equipment through the input terminal.

Signal conditioning:The collected signal is processed by conditioning circuits such as filtering and amplification to eliminate noise,interference and improve the accuracy of the signal.

A/D conversion:The conditioned analog signal is converted into a digital signal by the A/D converter for processing by the PLC or other control systems.

Data transmission:The converted digital signal is transmitted to the PLC or other control systems through the communication interface to achieve real-time monitoring and control of data.
