PIC microcontroller used in the industrial field, its power supply switching power supply and B0505 isolation module, anti-interference performance is better, feasible?
Isolation is not directly related to interference immunityIf the interference source cannot be removed and the interference source is removed, the transmission path is an effective method. The power supply interference can be considered using a power filter
Definitely better. What about someone else developing this power module? Directly with the switching power supply!
Which model you use PIC, switching power supply to the chip power supply, no problem, the key is to add single-chip power filter to do a good job.Relay output should be optically isolated and so on. B0505 output measurement must have a small load, and input and output must add filter capacitor, otherwise the interference is very big.
