Moxa NPort 5250AI-M12 - -25 to 55 C

The Moxa NPort 5000AI-M12 series is purpose-built for rugged railway and wayside environments where extreme vibration, electrical noise, and wide temperature ranges are common. With robust M12 connectors, an IP40-rated metal enclosure, and full EN 50155 and EN 50121-4 compliance, these serial device servers ensure reliable Ethernet networking for legacy serial devices onboard trains or trackside systems.

Equipped with 2 kV galvanic isolation, secure HTTPS management, SNMPv3 support, and support for all major OS platforms including Windows, Linux, and macOS, the NPort 5000AI-M12 provides fast deployment, advanced alerting, and simplified configuration via its 3-step web interface.
