G20 M-Bus MODBUS Ethernet 10/100MB 1xRS232/RS485 Gateway
- M-Bus MODBUS TCP/RTU Ethernet 10/100MB 2xRS232/RS485 Gateway
Product description
The G20 M-Bus to Modbus gateway is a complete device consisting of both hardware and software solutions. It enables data transmission between M-Bus protocol devices and Modbus serial devices (Modbus TCP, Modbus RTU) within a LAN network. It is well-suited for industrial environments and beyond. The G20 device supports up to 10 M-Bus devices, includes one RS232/RS485 port, a Fast Ethernet RJ45 connector, and offers quick and simple configuration via dedicated software. It is powered by an ESP32 microcontroller, operates with a 12–30 VDC power supply, features low power consumption (<1 W), and complies with the highest security standards.
