DC 12V 24V 433M Wireless RS485 IO Point-to-Point Master-Slave RF Transceiver Relay Swicth Board for Water Pump LED PTZ PLC (2 PCS (Transceiver))

Product Name:4DI-DO 433M Wireless RS485 Bus Relay Module RF Master-Slave Networking Remote IO Swicth Board for PLC Industrial EquipmentPackage inlcuded:1PCS/2PCS/5PCS433M RS485 Wireless Transceiver1PCS433M 4CH RS485 Wireless Relay(It is recommended to buy more than 2pcs, or a kit)（Please select the version you need）Description:Technical specifications:Supply voltage: DC 12V/24V;Standby current: default 20mA;Turn off the wireless transceiver function 12mA.Baud rate: 9600/19200/38400/115200, default 9600, N, 8, 1;Wireless operating frequency: 426MHz~508.5MHz, 16 frequency channels, channel spacing 5.5MHz, default 426MHz;Transmitting power:20dBm;Reception sensitivity: -113dBm;Wireless transmission distance: 800-1000m (unobstructed open space);Communication interface: RS485/Wireless,work independently without interfering with each other;Up to 63 modules can be used in cascade by modifying the 485 address (for more than 16 please use an RS485 repeater).Size: 144 X 92 X 40.5MM;Weight: 182g .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.For more information, please contact meApplicationPLC IO expansion boardSmart Home,Home Automation ,Wiser Home;PTZ CameraSecurity MonitoringIdentification system;IP CameraLED Lamp DriversAutomatic curtain controlWiring Diagram:Typical applications:Wireless Remote IO:1 RS485 address must be the same2 Wireless frequency Bands must be the same3 Wireless switch is Enabled(DIP Switch OFF)4 Enable Wireless Remote IO Sender(Register 0X00F5>0)5 Enable Wireless Remote IO Receive(Register 0X00F6=1)For use with RT5BF01:

• RT5BF01 wireless transmission module, based on the 433M frequency band development, can be RS485 received data signal into wireless signal, can be within a certain distance and the other end of the wireless transmission module for wireless communication, the other end of the wireless transmission module received wireless signal, and then converted into RS485 signal output
• Users can use multiple wireless transmission modules for data transmission without the need to lay too many long signal transmission lines. The modules only need to be powered on and connected to RS485 devices to achieve mutual data transmission, which is very convenient for users to operate RS485 devices at the remote end and effectively avoid the inability to transmit data due to rusty, broken or poor contact signal lines
• Wireless transmission distance: 800-1000m (unobstructed open space);
• Radio frequency of the module = channel * 5.5MHz + 426MHz
• Up to 63 modules can be used in cascade by modifying the 485 address (for more than 16 please use an RS485 repeater).
