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

What is the difference between analog output and digital output

The output of the analog signal is a continuous waveform, according to the size of the instantaneous value, directly acting on the load, such as the computer sound card output, the waveform is as follows:

The output of the digital signal is high and low, and the load side needs a digital processing circuit to further convert the received pulse into the required signal
