Moxa MB3270 Modbus TCP Gateway

The Moxa MB3270 MGate Modbus TCP Gateway is a 2-port bridge that links Modbus TCP networks with devices that communicate over RS-232, RS-422, or RS-485 serial interfaces. It functions as a gateway between Ethernet-based Modbus TCP masters and serial Modbus devices, enabling bi-directional communication across protocols for field devices on a single network. With two serial ports, you can connect two separate serial devices or networks to a Modbus TCP network, expanding your integration options in automated environments. The unit is powered from 12–48 VDC and draws up to 435 mA, suitable for use with common industrial power supplies and in mounted installations. By bridging Modbus TCP to serial Modbus devices, the MB3270 simplifies integration projects that mix Ethernet and field devices across factory floors. It accommodates two serial channels, offering flexibility to connect multiple serial devices to a single Modbus TCP network. This combination of two ports and a wide input voltage makes it suitable for on-site installations with varying power supplies.
