(as of Jan 26, 2024 10:03:41 UTC – Details)

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.
