The Moxa MGate MB3480 is a 4-port Modbus gateway designed to bridge Modbus serial networks with Modbus TCP systems. It’s a practical way to bring multiple Modbus RTU/ASCII devices into Ethernet-based SCADA or control systems without ripping out proven field gear.

Why We Love This Product

• Four ports provide higher density—ideal for cabinets with multiple Modbus serial segments
• Clean bridge between Modbus serial devices and Modbus TCP applications
• Helps modernise networks without replacing Modbus RTU/ASCII field devices
• Strong choice for staged upgrades and brownfield industrial environments

How Our Customers Use It

• Connecting Modbus RTU meters, drives, and sensors into Modbus TCP SCADA systems
• Consolidating multiple serial lines into a single Ethernet backbone
• Upgrading plants and utilities while keeping existing Modbus devices in service
• Creating cleaner architectures for monitoring, reporting, and remote maintenance

Choosing Tips

• Choose MB3480 when you need higher port density (4 ports) for multiple Modbus serial segments
• If you only need 1 or 2 serial ports, the MB3180/MB3280 models can be a better fit
• If you need advanced features or harsher environment rating, choose the corresponding “advanced” gateway variant
