MOXA Gateway, 2 Communication Ports, Ethernet Media Interface - MGate MB3280

This gateway connects Ethernet networks to serial devices, enabling protocol translation and remote serial communications in industrial settings. It supports RS232, RS422 and RS485 interfaces and is designed for continuous operation across standard industrial voltage ranges, making it suitable for automation, electronics and electrical system integration.

Features and Benefits:

• Two communication ports provide simultaneous multi-device access
• Operates across 12V to 48V to suit varied power systems
• Rated for 0 to 60°C to withstand elevated ambient temperatures
• Ethernet media interface enables networked serial conversion
• Meets EMC standards for interference-controlled installations
• Surge and transient protections reduce interruption risk during disturbances

Applications

• Suitable for connecting serial field instruments to Ethernet SCADA
• Ideal for Modbus TCP to RTU conversions in plant networks
• Used with PLCs that require RS232/RS422/RS485 bridging
• Can be used for remote serial device server deployments over LAN

What environmental range can I expect for continuous operation?

It functions across a minimum temperature of 0°C up to a maximum of 60°C for continuous service in warmer plant areas.

Which serial interfaces are available for device connections?

It provides RS232, RS422 and RS485 ports to accommodate a broad array of industrial peripherals.

How does the unit handle electrical disturbances on supply and signal lines?

The design includes surge and transient protections with specified EFT, ESD and surge immunity levels to limit impact from power and signal transients.

What approvals or safety standards has it been assessed against?

Safety and electromagnetic conformity have been evaluated under international standards including IEC/UL 62368-1 and relevant EMC criteria.
