MGate MB3180/MB3280/MB3480 Series

MOXA MGate MB3180/ MB3280/ MB3480 Series Introduction

The Moxa MGate MB3180, MB3280, and MB3480 series are robust, long-term industrial Modbus gateways engineered to provide seamless serial-to-Ethernet communication. Designed for efficient conversion between Modbus TCP gateway and Modbus RTU/ASCII protocols, these Moxa industrial Ethernet gateways are key enablers for integrating legacy serial equipment into modern Ethernet-based control systems. As part of Moxa industrial Ethernet gateway portfolio, these models are ideal for diverse sectors such as factory automation and other demanding verticals that rely on reliable data flow and centralized control. Whether managing a single field device or coordinating a complex system of Modbus devices, the Moxa MGate MB3180 series, Moxa MGate MB3280 series, and Moxa MGate MB3480 series deliver smooth interoperability and optimized network performance. Built to ensure high reliability, scalability, and ease of integration, these protocol gateways are industrial-grade solutions that feature isolation protection, rugged housings, and wide temperature tolerance. They help bridge the gap between outdated serial devices and today’s Ethernet networks, future-proofing infrastructures and enhancing operational efficiency in mission-critical environments. Moxa MGate series stands as a trusted standard in industrial edge connectivity and offers users a fast and reliable path to edge integration with minimal configuration required.

All three MGate series, including Mgate MB3180 series, Mgate MB3280 series, and Mgate MB3480 series, are equipped to handle Modbus TCP and protocol conversions for Modbus RTU/ASCII. With auto device routing, they streamline network deployment by intelligently mapping serial devices via TCP ports or IP addresses. Each gateway includes a 10/100BaseT(X) Ethernet port with auto MDI/MDI-X support and allows quick and adaptable integration into existing Ethernet infrastructures. Designed for scalability, the series supports up to 16 concurrent Modbus TCP master connections, each capable of handling up to 32 request queues, resulting in fast and reliable data processing. For enhanced durability, the Moxa gateways feature 1.5 kV isolation protection to prevent electrical damage and ensure stable communication in electrically noisy environments. The Moxa industrial Ethernet gateways operate on a 12 to 48 VDC power input, suitable for flexible power configurations in diverse settings. The primary distinction among the models lies in their serial port configurations: the MB3180 is a Single-port model (RS-232/422/485), ideal for compact or simple setups with minimal serial connectivity needs, the MB3280 a dual-port variant, offering enhanced flexibility for medium-scale systems where more serial connections are required, and the MB3480 is the four-port version designed for high-density applications with multiple serial devices needing concurrent network access. Each model includes DB9 male connectors for easy device interfacing, and their sturdy IP30-rated metal enclosures ensure durability. Those MGate models support an operating temperature range from 0 to 60°C to allow for stable performance in harsh industrial conditions. These gateways are a modular and scalable solution for serial-to-Ethernet conversion to provide secure data exchange, rugged design, and industrial-grade functionality to meet modern automation and networking demands.
