Description

The Moxa MGate-MB3170-T is a 1-port advanced Modbus TCP gateway that converts between Modbus TCP and Modbus RTU/ASCII, letting serial masters and slaves integrate with Ethernet networks. It offers one software-selectable RS-232/422/485 serial port and two 10/100BaseT(X) RJ45 Ethernet ports with built-in Ethernet cascading, and the -T model is rated for a wide -40 to 75°C operating range.

With support for 32 client and 32 server connections, the gateway suits industrial automation deployments that mix legacy serial devices with modern Ethernet infrastructure. Emergency request tunnels help maintain QoS control, embedded Modbus traffic monitoring simplifies troubleshooting, and security features include HTTPS (TLS 1.2), SNMPv3 and AES encryption. A 12 to 48 VDC input and IP30 plastic housing make it straightforward to install in control cabinets.
