Module RF 920 MHz Modbus RTU 1 khe cắm I/O ICP DAS RFU-IO-920 CR

RFU-IO-920 is a 920 MHz RF wireless I/O unit that uses the Modbus communication protocol. A remote Modbus master can use a 920 MHz wireless converter, such as the RFU-920, to convert Modbus commands into 920 MHz signals to control the I/O module on the RFU-IO-920, thereby implementing a wireless I/O solution. The RFU-IO-920 can achieve a transmission distance of 300 meters at a wireless baud rate of 125 kbps in a line-of-sight environment. To address potential environmental interference, the RFU-IO-920 offers multiple wireless baud rate options, ranging from 5 k bps to 250 kbps, allowing users to make adjustments. Additionally, users can adjust the wireless channel and group ID to avoid interference between adjacent 920 MHz networks. The RFU-IO-920 supports repeater mode to overcome communication distance and dead zone issues. The RFU-IO-920 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.
