Moxa MGate MB3170 1-Port Modbus Gateway

Industrial Modbus gateway

The Moxa MGate MB3170 is a one-port gateway that converts Modbus TCP packets to serial signals for industrial automation networks. It operates reliably across a 0 to 60°C temperature range and fits into compact cabinets with its 3.51 x 1.14 x 4.9 inch form factor. The unit provides a single Ethernet hardware interface for integration with existing control systems. This new device suits engineers bridging field devices to TCP/IP infrastructure.

For serial fieldbus integration

This gateway suits installers who need to connect one Modbus serial device to an Ethernet backbone without additional ports. It is not for projects that require multiple simultaneous serial connections or redundant network paths. Buyers needing isolated serial interfaces or expanded port density should evaluate alternative multi-port gateways. The classic style housing supports standard DIN-rail mounting in control panels.

Single-port Modbus TCP conversion

The defining specification is the single-port capacity that handles one Modbus TCP to serial translation path. This constraint determines whether the unit matches the device count in your application. The 0 to 60°C operating window supports typical industrial environments without active cooling. First listed by the manufacturer in 2023, the MGate 3170 series targets focused protocol conversion tasks.
