The MOXA NPort 6650-16-2AC-G2 is a 16-port secure terminal server designed for industrial users who need flexible serial support and a medium port count, while also preferring the 2AC package variant for rack or cabinet deployment. As part of the NPort 6650 branch, it supports RS-232, RS-422, and RS-485, making it better suited than the 6610 family to mixed serial environments where different legacy device types coexist. This makes it a strong fit for applications such as industrial automation, building management, process control, telemetry, machine communications, utility monitoring, and transport infrastructure, where a single platform often needs to connect HMIs, PLCs, meters, RTUs, serial consoles, and field devices with varying serial standards. Because this SKU includes 2 power cables and operates in the standard -10 to 60°C range, it is particularly well suited to managed indoor racks, control rooms, and panel-based deployments that value deployment convenience and consistent power-cord provisioning.
What differentiates the NPort 6650-16-2AC-G2 most clearly is its balance of port density, serial flexibility, and standard-temperature rack suitability. Compared with the 6650-8-2AC-G2, it offers double the serial capacity for more device-dense cabinets. Compared with the 6650-32-2AC-G2, it is often the more efficient option where 32 ports would be excessive. Compared with the 6610-16-2AC-G2, its real advantage is support for RS-422 and RS-485, including automatic data direction control and software-adjustable termination and pull high/low resistors, which make it more suitable for multidrop serial networks and longer field runs. It also benefits from the shared G2 security feature set, including Secure Boot, HTTPS with TLS 1.2/1.3, SSHv2, SNMPv3, RADIUS, TACACS+, and strong certificate support, helping serial infrastructure fit more securely into modern Ethernet networks. For organisations modernising legacy serial estates without giving up flexibility, the NPort 6650-16-2AC-G2 is one of the strongest mid-range options in the family.
