Description

The MGate MB3470 G2 is a 4‑port Modbus serial‑to‑Ethernet gateway that links Modbus RTU/ASCII devices to Modbus TCP networks. This TB variant uses 5‑pin terminal block connectors for each serial port and includes dual 10/100 RJ45 ports for easy daisy‑chain deployment. Built for harsh industrial environments, it features a -40 to 75°C operating range, DIN‑rail mounting, and a rugged metal housing. Moxa backs the product with a long industry‑leading warranty for peace of mind. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

FAQs

Q: What does the MGate MB3470 G2 do?
A: It bridges Modbus RTU/ASCII serial devices to Ethernet by converting to and from Modbus TCP, allowing legacy instruments and PLCs to be monitored and controlled over IP networks.

Q: How many serial devices can it connect?
A: It provides four independent RS‑422/485 serial ports. Each port can host multiple Modbus RTU/ASCII slaves on the same bus, subject to your serial topology and timing.

Q: What is special about the TB‑G2‑T variant?
A: TB indicates 5‑pin terminal block serial connectors, G2 adds dual RJ45 Ethernet for daisy chain/redundancy, and the T model supports an extended -40 to 75°C operating temperature.

Q: Does it support redundant or resilient Ethernet topologies?
A: Yes. The dual 10/100 RJ45 ports include an integrated 2‑port switch for daisy‑chain deployments and simpler network resilience without needing extra switches at each node.

Q: How is it managed and secured?
A: You can configure it via a web console or CLI, and monitor via SNMP. It supports typical industrial gateway security options such as user authentication and encrypted management sessions.

Q: Can I purchase this in Australia from IP Trading?
A: Yes. IP Trading is an Australian supplier for Moxa solutions and can provide quotes, stock availability, and technical guidance for the MGate MB3470 series.
