1, the Digital Input is the logic input (Digital Input, abbreviated as DI), also known as the switch input. For example, if you want to give a frequency converter a start signal (button on or relay on), then this signal is a digital input signal to the frequency converter. Switch input only on and off these two states, generally switch, button, limit switch, proximity switch. 

2, Digital Output (DO), Analog Input (AI), Analog Output (AO). For example, the speed of the frequency converter is the analog input, and the speed and current feedback of the frequency converter is the analog output
