![]() ![]() For wireless SCADA and wireless RTUs, order the RV-M21 with the GPIO interface or the Flexible IO (FIO) interface.Ĭonnect the GPIO terminal on the Tech Series radio to the right Sensors to Monitor in remote zones.īoats, Green Houses, Forests, and many places should be monitored to save them. The RV-M21 utilizes the Tech Series front panel has a myriad of IO options and some panes can be used as Wireless Remote Terminal Units. UHF and VHF 2 watt RV-M22 version are also available. The miniature RV-M22 is available in the 902-928MHz ISM band. The communication range is typically 1-10 miles, or 20 miles in open areas. MODBUS commands work with these radios, and the PLC or Master connect to the radio’s serial port to talk over-the-air to other radios with GPIO. Those GPIO and FIO interface options are RTUs built into this data radio. The RV-M22 has the same GPIO terminal interface option as the RV-M21 has. That green connector is the GPIO terminal block.įor License Free RF band use, the RV-M22 is a license free 915MHz RTU or serial data transceiver. ![]() GPIO pin are configurable as Digital input or outputs, Switched open drain outputs do enable relays, or Switched DC power output to drive, lights, relays, valves, or any DC powered item. The M21 is available with 1-5 watts RF output in VHF, UHF and 220MHz bands. GPIO pins can be configured to: switch DC power, read analog inputs, read 4-20mA in, or be a digital input. The General Purpose IO (GPIO) pins can be controlled with MODBUS commands. ![]() The M21 combine the functions of an RTU with a built-in data radio rodem to provide a cost-effective and powerful solution for various industries. The RV-M21 RTU has a GPIO interface to make it a RTU Slave Device:Ī M21 smart radio modem is a innovative Wireless Remote Terminal Unit (RTU) A Wireless RTU with built-in Slave features such as Raveon’s RV-M21 Tech Series telemetry modems be a Slave Device in a remote area. Connect an RTU radio to the right Sensors to Monitor in remote zones.Ī wireless Slave Device is a wireless RTU, and it keeps the system efficient and save costs, and make easier to install and update. Wireless SCADA and Telemetry use radio modems to connect The Master Controller to the Slave Device. VHF and UHF radio frequencies over very long range communication ability, and with the fastest transmit / receive hundreds of thousands of meters and may be polled or report-in every day on a single radio channel. Wireless SCADA systems are common for telemetry, remote control, and power grid management. Raveon’s data radio products are well-suited for Wireless Remote Terminal Units (RTU) in the SCADA and telemetry industry.
