The Moxa MGate MB3270 is a 2-port advanced Modbus gateway for bridging Modbus serial networks to Modbus TCP systems. With a 0 to 60°C operating temperature range, it’s built for industrial environments where uptime matters and you want a more robust gateway option for your Modbus integration.

Why We Love This Product

• Two ports for connecting multiple Modbus RTU/ASCII serial segments into Modbus TCP
• Advanced gateway positioning for more demanding industrial deployments
• 0 to 60°C operating range fits typical OT cabinets and plant environments
• Great for modernisation projects where stability and long-term supportability are key

How Our Customers Use It

• Integrating Modbus RTU devices into Modbus TCP SCADA and monitoring systems
• Connecting multiple serial chains (e.g., meters/drives) into an Ethernet backbone
• Improving manageability and remote access for Modbus-heavy brownfield sites
• Reducing serial bottlenecks while keeping existing Modbus devices in service

Choosing Tips

• Choose MB3270 when you want a 2-port gateway with a 0 to 60°C rating and a more robust “advanced” option
• If you only need a basic bridge and your environment is straightforward, the MB3280 may be sufficient
• If you need more ports, move up to a 4-port Modbus gateway to avoid stacking multiple devices in one cabinet
