MOXA MGate MB3170I Industrial Ethernet Gateway
- Model: MGate MB3170I
MOXA MGate MB3170I INTRODUCTION
Industrial environments often depend on legacy serial
devices that need to communicate with modern Ethernet-based systems without
replacing existing equipment. The Moxa MGate MB3170I industrial Ethernet gateway is designed within Industrial Edge Connectivity to bridge Modbus
RTU/ASCII serial devices with Modbus TCP networks, enabling reliable data
exchange in marine, oil and gas, factory automation, and other industrial
applications. Supporting RS-232/422/485 communication through one serial port
and two 10/100BaseT(X) Ethernet ports, the Moxa MGate MB3170I gateway provides
flexible integration between field devices and Ethernet infrastructure. Its
support for Modbus TCP Client and Server functions, along with 2 kV serial
isolation, helps maintain stable communication in electrically demanding
environments. With simple deployment and dependable protocol conversion, this
gateway helps engineers modernize existing systems while improving network
visibility and operational efficiency. Review the Moxa MGate MB3170I datasheet
to explore specifications and application compatibility.
