The MOXA NPort 6650I-16-G2-T is a 16-port wide-temperature isolated secure terminal server built for harsh industrial environments where both electrical protection and environmental resilience are essential. With support for RS-232, RS-422, and RS-485, plus 2 kV isolation and a -40 to 75°C operating range, it is especially suitable for utility installations, harsh transport systems, exposed automation cabinets, industrial energy applications, and other field deployments where a normal indoor terminal server would not be robust enough. The 16-port density makes it a strong option for medium-sized rugged sites that need to integrate several serial devices without moving to a larger 32-port chassis. 

Compared with the 6650I-8-G2-T, it supports more endpoints and is better suited to centralised rugged cabinets. Compared with the 6650I-16-G2, it adds wide-temperature performance for harsher locations. Compared with the non-isolated 6650-16-G2-T, it adds extra protection through 2 kV isolation. It still includes the shared NPort G2 secure networking feature set, including Secure Boot, TLS 1.2/1.3, SSHv2, SNMPv3, RADIUS, TACACS+, one-click log collection, and application analysis, helping it address both cyber-security and maintenance efficiency. For harsh-environment serial networking projects that need a mid-range port count and stronger protection against electrical noise, the NPort 6650I-16-G2-T is a very strong fit.
