Overview
Moxa MGate MB3170-G2-T – Advanced 1-Port Modbus Gateway, Wide-Temperature
The Moxa MGate MB3170-G2-T connects a single serial device to Ethernet control systems and bridges
Modbus TCP, RTU and ASCII. Use transparent mode for pass-through, or agent mode
to poll devices, cache data, and serve SCADA with lower latency and higher determinism.
- Network flexibility Dual 10/100BaseT(X) RJ45 for cascade or dual-subnet architectures
- Ops-friendly Secure web console, DSU, diagnostics, traffic monitoring, one-click logs
- Industrial design 12–48 VDC dual power, relay output, IP30 metal, −40 to 75 °C
- Security HTTPS/TLS and SNMPv3 with modern ciphers; local authentication database
- Assurance High MTBF and 5-year warranty
Built for harsh sites and unconditioned enclosures, MB3170-G2-T delivers dependable Modbus
conversion with streamlined deployment and maintenance.
