What are the advantages of RS485?

RS485 has advantages like strong anti - interference ability due to differential signal transmission, long - distance communication capability, and the ability to support multiple devices on a single bus for distributed control systems.
Typically, an RS485 bus can support up to 32 devices. However, with the use of repeaters or special drivers, the number of connected devices can be increased, depending on the specific application requirements.
RS485 is more suitable for medium - speed data transfer. While it can support data rates up to a few Mbps, it is not as fast as some other high - speed communication standards. But its reliability and long - distance capabilities make it ideal for industrial applications.
