Product Overview:
The N4RFA04 wireless RS485 relay module can read or control relay status via RS485 bus or 433M wireless, and can also read input status. The wireless is developed on the 433M band and can be used with the RT5BF01 wireless transmission module or with another N4RFA04 device using the Wireless Remote IO function.
In addition to the conventional RS485 control, users can use the N4RFA04 with the RT5BF01 wireless transmission module for data transmission, without the need to lay too many, too long signal transmission lines, the N4RFA04 module only needs to be powered on to achieve remote control of the upper computer, which is very convenient for users to operate the N4RFA04 device from a remote location, and effectively avoid signal lines due to rust, broken wires, poor contact, etc. It is also very convenient for the user to operate the N4RFA04 from a remote location.
The module can be set with 5 parameters via dip switches, simplifying the parameter setting process and making it very user-friendly. The parameters that can be set are the device address, RS485 switch, wireless switch, baud rate and channel, the settings of the dip switches can be found in the following selection table.
Radio frequency of the module = channel * 5.5MHz + 426MHz.
