The Moxa MGate MB3280 is a 2-port Modbus gateway that bridges Modbus serial networks with Modbus TCP systems. It’s a clean way to connect multiple Modbus RTU/ASCII device lines to Ethernet-based SCADA and monitoring platforms—without replacing your existing field devices.
Why We Love This Product
- Two ports—great for small to mid-sized cabinets with multiple Modbus serial segments
- Bridges Modbus RTU/ASCII devices into Modbus TCP networks
- Enables staged modernisation without ripping out proven Modbus field devices
- Good “right-sized” option between single-port and high-density gateway models
How Our Customers Use It
- Integrating Modbus RTU devices (meters, sensors, drives) into Modbus TCP SCADA
- Connecting two separate serial device chains into one Ethernet backbone
- Reducing serial-only limitations while keeping legacy devices running
- Building cleaner remote monitoring and maintenance workflows over IP
Choosing Tips
- Choose MB3280 when you need 2 Modbus serial ports bridged into Modbus TCP
- If you only need one serial port, the MB3180 is the simpler pick
- If you’re already at (or heading toward) multiple serial segments, consider the 4-port MB3480 to avoid rework later
