RFU-IO-433 is a 433 MHz RF wireless I/O unit that uses the Modbus communication protocol. A remote Modbus master can use a 433 MHz wireless converter, such as the RFU-433, to convert Modbus commands into 433 MHz signals to control the I/O module on the RFU-IO-433, thereby implementing a wireless I/O solution. The RFU-IO-433 can achieve a transmission distance of 300 meters at a wireless baud rate of 9600 bps in a line-of-sight environment. To address potential environmental interference, the RFU-IO-433 offers multiple wireless baud rate options, ranging from 57600 bps to 650 bps, allowing users to make adjustments. Additionally, users can adjust the wireless channel and group ID to avoid interference between adjacent 433 MHz networks. The RFU-IO-433 supports repeater mode to overcome communication distance and dead zone issues. The RFU-IO-433 also provides I/O pair-connection mode for remote I/O control without a host. These features can be configured via rotary and dip switches, making system maintenance and equipment replacement simple and convenient.
