RS485-Surge
Build Semiware into your application circuit
Summary
RS-485 uses differential signal negative logic. A logic "1" is represented by a voltage difference of +(2~6)V between the two lines; a logic "0" is represented by a voltage difference of -(2~6)V. The maximum data transmission rate of RS-485 is 10Mbps. It is widely used in industrial transmission, smart homes, and PTZ control for security equipment. These products are often placed outdoors and are highly susceptible to damage from induced lightning strikes, which can conduct from the main line to branch lines or vice versa.
Testing Standard:
8/20μs CM/DM 3KA
