The Moxa CN2650-16-2AC is a 16-port industrial terminal server that supports RS-232/422/485 interfaces and is designed for applications that demand maximum reliability and redundancy. Featuring dual LAN ports and dual AC power inputs, this model ensures continuous serial-to-Ethernet communication even under adverse conditions such as network or power failure.

With Redundant COM mode, the CN2650-16-2AC sends duplicate data over two independent networks to maintain connectivity. Dual-host redundancy allows a backup PC to seamlessly take over communication. Supported across Windows, Linux, UNIX, macOS, and Android, and equipped with comprehensive security protocols, this device is ideal for industrial automation, transportation systems, utilities, and infrastructure networks.

The robust metal housing, versatile mounting, and broad standards compliance underline the unit’s suitability for critical deployment environments. Its MTBF of over 442,000 hours guarantees long-term dependability.
