Moxa NPort 5400 Series – 4-Port RS-232/422/485 Serial Device Servers for Industrial Networks

The NPort 5400 Series by Moxa enables transparent and simultaneous network connectivity for up to four serial devices. With flexible independent port modes, dual DC power input, and optional isolation for harsh environments, it offers a versatile, reliable solution for modern industrial networking.

The built-in LCD screen on standard models makes setup fast and intuitive. Models with -T suffix support extended temperatures, and isolation models provide 2 kV protection on serial lines.
