Industrial Terminal Server
The Moxa CN2650I-16-2AC is a 16-port device server built for industrial automation and serial-to-Ethernet integration. It supports RS-232, RS-422, and RS-485 interfaces through DB9 connectors, enabling reliable connectivity for legacy equipment and remote sensors. Dual 100-200VAC power inputs with adapter and 2 KV isolation provide redundancy and protect connected systems from electrical noise. This unit suits engineers managing serial device networks in harsh environments.
Capacity and Headroom
Sixteen serial ports allow simultaneous connection of multiple PLCs, meters, or controllers without additional concentrators. The three supported electrical standards cover most common industrial protocols, though devices requiring proprietary interfaces will need conversion. Dual AC inputs ensure continued operation if one supply fails, yet the server lacks DC power options for substation or mobile deployments. Buyers needing more than sixteen ports or fibre uplink redundancy should consider alternative architectures.
Highlights
- 16 serial ports connect legacy equipment
- DB9 connectors support RS-232/422/485 protocols
- Dual 100-200VAC power inputs provide redundancy
- 2 kV isolation protects against voltage spikes

Questions about this item
Will the CN2650I-16-2AC connect my legacy RS-232 instruments alongside newer RS-422 or RS-485 gear on the same unit?
Yes, each of the 16 DB9 ports supports RS-232, RS-422 and RS-485 so you can mix serial standards without extra converters.
How can I confirm the dual 100-200VAC power inputs and 2 kV isolation are active after installation?
The front-panel LEDs show power status for both AC inputs; the isolation is a hardware feature present whenever the unit is powered.
