When the instrument or controller (TTL) is connected to the computer for communication, it is easy to produce zero potential mismatch, which will cause the signal to be unstable or the instrument accuracy to deteriorate. 2. The use environment is harsh, and the isolated module can effectively remove noise, and it is used in relatively demanding occasions. 3. Protect instruments, components and people from high voltage hazards. Package Included: 1* Isolated TTL to 485 module 1* 4P cable 2* Single head hexagonal copper column M3*6 2* M3 nut 2* M3*5 screws
