Why do you need to use isolated power in industrial communications?
In addition, between high and low voltage in order to avoid high-voltage equipment on the low-voltage equipment interference, or high and low pressure need to be separated, will be used to isolate.
if not isolated, and other devices together, it will cause other equipment to interfere with the communication equipment.
In simple terms, the need for isolation mainly involves: communication equipment on the power of the stability and anti-interference requirements are high,
