G30 - M-Bus to Modbus TCP/RTU Gateway (Ethernet + Wi-Fi + RS232/RS485)
New in
G30 - M-Bus to Modbus TCP/RTU Gateway (Ethernet + Wi-Fi + RS232/RS485)
- Wireless gateway connecting M-Bus meters to Modbus TCP/RTU systems.
Product Description
The Redisage G30 is a wireless version of the M-Bus to Modbus gateway, offering connection redundancy (Wi-Fi + Ethernet). It is designed for applications where running LAN cables to metering cabinets is difficult or cost-prohibitive.
The device automatically reads data from M-Bus meters and makes it available via the Modbus TCP protocol over Wi-Fi. Key features:
• Connectivity: Wi-Fi 2.4 GHz + Ethernet
• Function: M-Bus Master -> Modbus TCP/RTU Converter
• Flexibility: Ideal for retrofitting and remote cabinets
• Antenna: External SMA connector
• Configuration: Built-in Web Server

About G30
G30 – Wireless M-Bus Integration
The G30 Wireless M-Bus Gateway is the ultimate solution for modernizing metering infrastructure in existing buildings. Often, M-Bus meters are located in basements or shafts where wired Ethernet is unavailable. The G30 connects to these meters via the 2-wire M-Bus line and transmits the collected data wirelessly via Wi-Fi to the building management system (BMS).
Like the wired G20 model, the G30 acts as an autonomous M-Bus Master and protocol converter. It continuously polls the meters and updates its internal memory, which can be read by any Modbus TCP Client (e.g., SCADA) over Wi-Fi. The device also includes an Ethernet port for backup or configuration.
The robust SMA antenna connector ensures reliable communication even in difficult environments. The gateway supports advanced data mapping features, allowing you to select specific values (e.g., Energy, Volume, Flow Temp) from the complex M-Bus telegram.
Technical Specifications:- Wireless: Wi-Fi 2.4 GHz (802.11 b/g/n).
- Wired: Ethernet 10/100 Mbps.
- Conversion: M-Bus (Master) to Modbus TCP/RTU.
- Configuration: Web Interface (M-Bus scan & map).
- Antenna: External, SMA type.
