Module description:
1 RS422 interface, two-way communication. B Y Z A ultra far transmission 1000 meters
The 2 module has ESD 15KV protection.
3 onboard to increase the limit of 10 ohms current limiting current protection.
4 module with TVS diode. Anti lightning, peak voltage.
The 5 module has 120-ohm termination resistors, which can effectively reduce the interference of long-range communication.
