Please bosses under the guidance of the following the working principle of the module-CodePudding

CodePudding user response:

1. The input signal after Q1 switch control IRL1 light coupling work, operational amplifier LM358 do voltage follower output,
2. R4 as offset using,
3. The R5 current limiting is used,
4. The C1 and C2 bypass,
5. Add light coupling is to isolate the input and output,
