Feature: 1. [WIRELESS CONTROL] The wireless relay module can read or control the relay status via RS485 bus or 433M wireless, and can also read the input status. 2. [MATCHING DEVICES] Can be used with RT5BF01 wireless transmission module or other for N4RFA04 devices to use the wireless remote IO function. 3. [PARAMETER SETTING] The module can set 5 parameters through the dial switch, namely, device address, RS485 switch, wireless switch, baud rate and channel. 4. [WORKING RANGE] The wireless frequency range is 426-508.5MHz, the wireless transmission distance is 800-1000 meter (unobstructed open space). 5. [WIDE APPLICATION] Widely used in PLC IO expansion board, smart home, security monitoring, identification system, network camera, LED light driver, etc. 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). Specification: Item Type: Wireless Relay Module Standby Current: Default 20mA, turn off wireless transceiver function 12mA Baud Rate: 9600 19200 38400 115200, default 9600, N, 8, 1 Wireless Working Frequency: 426MHz-508.5MHz, 16 channels, channel interval 5.5MHz, default 426MHz Transmission Power: 20dBm Receiving Sensitivity: -113dBm Wireless Transmission Distance: 800-1000 meters (Unobstructed open space) Product Size: Approx. 144 x 92 x 40.5mm / 5.7 x 3.6 x 1.6in Package List: 1 x Relay Module1 x Antenna Note: 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 See more
