How to Use: Communication interface can be installed: RS485 wireless, working independently and not interfering with each other;You can cascade up to 63 modules by modifying the 485 address (use RS485 repeaters for more than 16).
Package List: 1 x Relay Module 1 x Antenna
Notice: In addition to the conventional RS485 control, users can also use N4RFA04 with RT5BF01 wireless transmission module for data transmission without laying too many and too long transmission lines. The N4RFA04 module only needs to be powered on to realize remote control. It is very convenient for users to remotely operate N4RFA04 equipment, effectively avoid rust, broken line, poor contact, etc. of the line, and also very convenient for users to operate N4RFA04 from a remote place.
