Description

The Moxa MGate MB3470-TB-G2-T is a 4-port advanced serial-to-Ethernet Modbus gateway that connects Modbus RTU/ASCII serial devices to Modbus TCP networks. It provides 4 x RS-232/422/485 serial ports on 5-pin spring-type terminal blocks and dual RJ45 Ethernet ports, and its wide-temperature rating of -40 to 75°C suits harsh industrial environments.

The gateway supports Modbus RTU/ASCII/TCP master and slave operation in transparent or agent (poll and cache) mode. Built-in Modbus communication test tools and traffic diagnostics simplify commissioning and troubleshooting, while HTTPS (TLS 1.2) and SNMPv3 support help secure device management. Redundant dual DC power inputs and a relay output add resilience for continuous operation.

Features

- Supports Modbus RTU/ASCII/TCP master and slave modes
- Transparent or agent (poll and cache) operating mode
- Built-in Modbus communication test tools that run independently of external software
- Modbus diagnostics and traffic monitoring for easier troubleshooting
- HTTPS (TLS 1.2) and SNMPv3 security support
- Dual Ethernet ports for cascade or dual-subnet configuration
- Wide operating temperature range for harsh environments
